Oracle Calendar Server Designate to Microsoft Exchange Delegate Migration

Trying to get Outlook Delegate Permissions:

from Oracle Calendar Server Designate Access Rights

can be tough.

We just made the Oracle Calendar DESIGNATE to Microsoft Exchange DELEGATE migration simpler (and removed PFDAVAdmin from the equation, while it worked it was a complicated pain in the neck).

Now under the processing stage check box in our insertion code is an option called "Set Delegates"

It takes a converted designates export file, as we've previously told you how to build, and will set those according to these rules:

• Users must be VALIDATED
• NO delegates are set to see PRIVATE items on Exchange
• NO delegates are set to receive Meeting Invitations
• There is no UNDO for Delegates
  

Here is the “get-mailbox fl” command that shows Russ has been set as Zyg's delegate

In the database:

If Delegate is true then the user is assigned as an EDITOR

If ReadONLY is set to true, then the user is assigned as a REVIEWER

If ReadONLY is set to FALSE, then the user is assigned to AUTHOR

Here is the commandlet to WIPE OUT ALL DELEGATES, regardless of who set them:

get-mailbox -ResultSize unlimited where {$_.Servername -like "Server" -and $_.GrantSendOnBehalfTo -ne {}} Set-Mailbox -GrantSendOnBehalfTo $null

(Remember to change “SERVER” to your server name!)

We suggest you use this in your TEST environment for verification purposes.

Insert Holidays Server-Side into Exchange 2007

Done.

Ship it.

The Sumatra Utilities for Exchange 2007 are now available for download.

Keep in mind, they won't just insert holidays for the 2010 calendar year, they'll also let you:

• Check for broken meetings in your conference rooms
• Gracefully remove terminated user meetings
• Extract resource use data you can then analyze in a spreadsheet (not full ResourceWatch but it gives you easy access to data that was hard to get before)
• And if you want to start using them to develop your own applications (we've got one business school that's done that and another evaluating), we can do that as well.

Sumatra Utilities documentation is out

A quick update on the Sumatra Utilities for Exchange 2007: we've field proven them in an East Coast medical school with over 8000 users.

Insertion of 10 holidays for these users took about three hours.

We consider that a success.

We're running our final regression testing on them now but we can give you the link to the documentation (Word format).

http://www.sumatra.com/Sumatra%20Utilities%20Manual.doc

Stay tuned.

Impersonation in Exchange 2010

Quick tip: Impersonation in Exchange 2010 has morphed from setting ACLs to Role Based Access Control (RBAC). It could not be easier to impersonate users in the entire domain:

new-ManagementRoleAssignment -Name:_suImpersonateRole
-Role:ApplicationImpersonation -User:'xxx@xxx.xxx'

Here is a link to a Microsoft TechNet article: Understanding Role Based Access Control

Sumatra Utilities for E2K7 available next week

We're not trying to drive you crazy -- just trying to make sure everything works and getting our legalese squared away.

The Sumatra Utilities for Exchange 2007 (including holiday server-side insertion capability) will be available next week.

Keep checking here for updates.

FullAccess fails with the error: The specified folder could not be found in the store.

I have been banging my head against the Exchange 2007 brick wall for the last month over the error: "The specified folder could not be found in the store."

Sumatra's conference room analysis tool's Exchange Web Service calendar folder "FindItem" request failed for about 5% of the rooms at one client. Other clients do not have this problem! The service account had FullAccess to all rooms. All conference rooms were on the same Exchange mailbox server, in the same OU, configured to autoaccept. Some had delegates, some did not.

The client could use the service account credentials to access the calendars via OWA. Was it a corrupted meeting? We changed FindItem's interval. No luck. Was EWS timing out over a large mailbox? Increased the HTTP timeout. No luck. Our FindItem requet uses the DistinguishedFolderID. We called GetFolder to find the FolderID. It failed on the inbox with the message "The specified object was not found in the store", and for the calendar folder with the message "The specified folder could not be found in the store".

Ahha! The permissions were not inherited. We added "InheritanceType: All" and it worked. Here is the syntax:

Get-Mailbox -filter {isResource -eq $True} -Resultsize unlimited
Add-MailboxPermission -User: xxxx -AccessRights: FullAccess
-InheritanceType: All

Holiday insertion server-side in Exchange 2007

Remember the Sumatra Utilities for Exchange 2003 and their beloved server-side holiday insertion capability?

And you remember how every year you ask us if we've done it for Exchange 2007?

Well, we (finally) rebuilt it for Exchange Web Services. Check out this example.

Friends of Sumatra can use this at no charge (you all know who you are) so just ask us and we'll send it out.

For everyone else we're actually going to charge for the capability this time.

Which brings me to the purpose of this posting: If you have any preferences on how we should do this -- drop us a line. If you do not know our emails you can use our contact form.

Oh yeah -- this is also going to include the broken meeting check, the terminated user utility, and the interface for managing conference room statistics (the full application for the last one will be a separate follow-on offering).

500 errors on test insertion into Exchange 2007?

When you get a "500" error on validation or a test insertion, please verify your:

1. CAS/MBX boxes are members of Windows Authorization Access Group
2. Impersonation permissions stuck (and are not denied) through Active Directory Sites & Services
3. Service Account is NOT a member of any Exchange Admin Group/Domain Admin group

Oracle Calendar / Meeting Maker to Google Calendar Migration

OK, for street cred, we did a Meeting Maker (it will work with Oracle or Sun Java Calendar as well) to Google Calendar migration extension.


Keep in mind, we'll morph this as it makes contact with the real world. Here's how it currently works.


We use our tools to produce ICS files. Not a problem for appointments, but for meetings the idea is to make them live.


Here's how we do it. We insert the emails of the attendees into the OWNER's agenda.

She or he can find these really easily after inserting into Google by searching for "(re-propose)" Open it and highlight the emails, copy / drag them into "Guests"

SAVE it and SEND it:
Voila, live meetings, simple, inexpensive, and done.

There's a few issues: I think we'll load all the To-Dos into an All-Day Event on the day of the migration (since Google doesn't have an import/export capability for Tasks yet).

We migrate Contacts via CSV files.

We looked at automated ways of uploading, but the Google Calendar API does not support uploading via ICS. So we're sitting on XML uploads via cURL until we have a corporate customer (which means we are not holding our breath).

We think it's more likely a corporate customer is going to want to get OUT of Google Calendar and into Exchange (you listening, Roche?).

NB: We only handle "re-propose" for meetings which have not yet ENDED -- any other meetings get turned into appointments in everyone's calendar.

Smartphones and your calendar server migration

We go over this a lot with folks and it's worth blogging about.

Let's say you're switching your calendar server and you've got BlackBerrys, Smartphones, ancient PDAs, whatever connected to your old server. And you want to use the same product when you're done in your NEW environment (let's call it Exchange).

Our recommendation is that as part of your migration process you blank out your calendars in your source system and re-synch completely on your target.

Why? Because the synch usually keeps track based on something called UIDs (or Universal Identification Numbers). You change your calendar server, you change your UIDs, and if you're not careful your Smartphone will get data from BOTH systems (and this is a hassle).

While migration is going on we strongly recommend turning off your BlackBerry server. Why? Sumatra generates a lot of email as part of re-creating end-user calendars in Outlook. While Sumatra’s insertion technology removes almost all of that email from end user’s in boxes, it can not remove those messages delivered to your device via the BlackBerry Exchange Server. So depending on your migration option your BlackBerry users will either be flooded with a lot of email (no EventSink) or some email (EventSink).

Since your BlackBerrys, Palms, or WindowsMobile PCs is synched with a system that is obsolescing – you will need to clear the calendars when you shut down your Oracle Calendar / Meeting Maker / Sun Java Calendar / etc. server, then have your users re-synch after the migration is completed.

BlackBerry

For clearing the calendar on the Blackberry – see the following webpage:
http://www.blackberry.com/knowledgecenterpublic/livelink.exe/fetch/2000/8021/7925/8142/How_To_-_Reset_the_BlackBerry_device_calendar.html?nodeid=1201826&vernum=1

Palm

For clearing the calendar on a Palm OS, you might use the Purge function:
http://kb.palm.com/SRVS/CGI-BIN/WEBCGI.EXE?New,kb=PalmSupportKB,CASE=obj(5029),ts=Palm_External200173

Windows Mobile (Pocket PC)
For Windows Mobile, you can:
· Open ActiveSync
· Double Click on Calendar.
· Change the settings such that it syncs only 0 past and 0 future appointments.
· SYNC - this will clear all calendar items on the IPAQ / most other Pocket PCs.
Note: Some earlier ActiveSync versions attempt to interpret the default Sumatra Category as a date field. If you have Windows Mobile PCs you should remove the keyword AFTER you have done your quality assurance testing on the migration. Sumatra also has a COM add-in for Outlook that will accomplish the same thing on a user-by-user basis.

NotifyLink

Updated September 10, 2009 with info from Notify Technology.

Migration for NotifyLink Enterprise Server (NLES) Users with recent versions.

An administrator must:

1. Make sure the NLES server and device software are up to date.
2. Create the new mail and PIM servers
3. Open the user administration list and for each user to be moved, select the “Edit User” button.
4. On the “Edit User” page, switch the email and PIM servers to the new servers that were created.
5. This should all be done after the actual migration is complete on the server side. Notify Tech claims their software should handle the rest. It should re-prime accounts and issue full resynchronization commands. The device PIM stores will be automatically cleared and reloaded with the new account info.
   
   Earlier versions of their software ran a more complicated, non-automatic process.

"Run-As" for Vista/Windows Server 2008

Wondering how you can get the "Run-As" back in the context menus for Vista and Windows Server 2008? Thanks to Sysinternals Mark Russinovich and Jon Schwartz it's easy. Their tool ShellRunAs is located here: (http://technet.microsoft.com/en-us/sysinternals/cc300361.aspx)

It's easy to use - Unzip and move shellrunas into windows\system32. Then type the following in the start/Run command line: shellrunas /reg. That's it. Right click on an item to see "Run as different user"

Gmail went down again on September 1, 2009.

My schadenfreude finally met my Weltanschauung.

Of course, I got THIS one at 3:43 PM PDT which was DARNED confusing:

So with everyone who's been looking to migrate into Google Calendar: be really careful what you ask for.

And to everyone already there: migrating OUT of Google Calendar into Exchange is a LOT easier than a real time server-side synch between the two.

Migrating Resource Scheduler Data into Exchange 2007

No sooner was one of us back from the Seattle Opera Ring Cycle (Janice Baird rocks!) than we got one of our favorite types of inquiries: Can we get data out of Resource Scheduler and into Exchange 2007 native?

Short answer: Yes.


If you're primarily using Resource Scheduler to book rooms (something Exchange 2003 did not do well) and want to take advantage of the newer (and better) capability in Exchange 2007, this is very doable. We've already figured out how the Resource Scheduler SQL schema is structured and can simply modify and re-propose the meetings with mailbox-enabled resources on E2K7. With this knowledge if you want to try to write this code yourselves, go ahead, but be forewarned, it is harder than you think.


In contrast to the hundreds of calendar migrations we've done, this is more of an informed consent clinical trial right now, but if you're interested drop us a line. The more interest there is the more likely it is we'll proceed with development.


You should also read: Resource scheduling in Exchange Server 2007 and Using Exchange 2007 for Resource Booking. For the truly adventurous and technically adept, check out How to Create or Remove Custom Resource Properties.

Sun Java Calendar, aka iPlanet, full-state migration to Exchange 2007

Sun Java Calendar Server, previously known as Sun ONE Calendar Server, and before that iPlanet Calendar Server (the darn thing has had more names than that "Diddy" guy) is now among our full-state, server-side migrations into Exchange 2007.


It kept popping up sporadically and just came around for a 5000 user migration. Then this opportunity turned into a 500 user migration with a budget that would cover a few blended drinks at Starbuck's and we were wondering how we were going to make any money out of it. As any of you know, we're market-driven.

So here's how it's working.

We use Sun's WCAP protocol to extract the calendar and task data.

We run it through our conversion tools to morph into our intermediate format from which we can map user IDs and do all sorts of other wondrous things.

Then we insert it into Exchange 2007 using EWS (we parted ways with the now-deprecated CDO way back after Exchange 2003).

A few notes:

Recurrence patterns in Sun Java Calendar are a 1:1 match for Outlook, so we have thus far not seen any exceptions.


We can actually handle attachments. The big issue here is not the technical aspects of attachments, but the logistical ones. Often when running a migration the amount of data can cause low-set quotas to be exceeded pretty quickly, and you don't want to run into that at 2:00 AM on a Saturday. So we recommend extracting to a common directory and just passing a link to the attachment in the Agenda field. If you can avoid migrating them entirely, so much the better.

SJC has a limit on "on-going" meetings. Outlook / Exchange do not -- so we simply set an SJC "ongoing" meeting to an Outlook meeting with No End Date.

A word on versions.

We do version 6.x. With a little bit of prodding (in the commercial sense) we could be convinced to make it work for Sun ONE / iPlanet 5.x.

Future version 7 (now in beta) - we are not guaranteeing. You want to check out Calendar Server 6 and Calendar Server 7 Comparison and Coexistence. Since Sun does not currently have a migration path between 6 and 7 we're not anticipating we'll need to have a version 7 migration to Exchange path for a while.

However, since Calendar Server 7 us apparently based on MySQL (see : Best Practices for Backing up and Restoring MySQL Databases in Calendar Server Deployments) we are very optimistic a full-state migration will just involve reading their database and morphing it into our schema.

Bigger question is: Will Version 7 even make it out the door when the Oracle acquisition is final? Oracle is not likely to keep supporting two past-their-prime calendar systems.

Meeting Maker to Google Calendar field test results

It's been a productive few weeks.


We just used our existing iCalendar tools to export a few Meeting Maker calendars for a site that wanted to go into Google Calendar.


With a little surgery (removing our Time Zone DST definitions) and using the Zulu time option, the data actually imports pretty well. The above example is real-world data.


Now there's a couple of things it doesn't do right out of the box: banners are currently off kilter (this is an easy fix), and we're not sure it's worth replicating the full set of state data for guests (because nobody else does it and everybody going into Google Calendar is price-constrained), but it's not that hard to at least put the guest list into the Description field.

As you know, we actively solicit your feedback.

Migrating to/from Lotus Notes/Domino Calendar from/to something else?

It was a glorious summer day in Boston and of course I could think only of calendars.

Having come off installing Yellow Dog Linux on my PS3, I thought "How much geekier can I make the day?" OK, I actually thought "how soon can I fire up the grill?" but the lack of high-quality Chilean sea bass caused me to re-think my plans.

So given that one of the development guys warned me that there was no way I could possibly set up a Lotus Domino configuration on Linux by my own self, I had to prove him absolutely correct and generate this sample calendar. (BTW: If you try doing this on Fedora, remember to shutdown sendmail or Domino won't come up due to a port conflict.)

Needless to say - yes, this means we're looking at full-state migrations out of Lotus Notes and into other less "legacy" environments. Our first impetus is someone who wants to take a few thousand Meeting Maker seats and put them INTO Lotus Notes, but we can work in stages.

More later.

BlackBerry Permissions and Exchange Server-Side Holiday insertion

So remember a few days ago when we told you about a great simplification in setting up permissions?

Basically, and you should not be too surprised at this, the permission for BES admin are really really close to the permissions necessary for inserting holidays or running a full-state calendar migration.

Check out this post:

http://forums.crackberry.com/f50/exchange-2007-bes-install-guide-942/

which advises setting permissions as follows:

get-mailboxserver add-exchangeadministrator
BESAdmin –role ViewOnlyAdmin

get-mailboxserver add-adpermission –user
BESAdmin –accessrights ExtendedRight –extendedrights Send-As, Receive-As,
ms-Exch-Store-Admin

And then tells you to follow up with:

Open Active Directory and from the View menu select "Advanced Features". Then
go to each user that will be added to the BES and open their properties, go to
the security tab and add the user BESadmin and add the security permission "Send
As". (This will overcome some MS patches that prevent BES sending emails).
Methods are available to add BESadmin "Send As" rights to all users if required
but this method ensures only the required users have permissions added.

Make BESadmin a local Administrator of the server where you will be
installing the BES software. This is done by right mouse clicking my computer
and selecting “Manage”. From Computer Management expand “Local Users &
Groups” and select Groups. From Groups double click “Administrators” and add
BESadmin.

This is pretty much what we tell you to do in setting up a service account for running a Sumatra migration or inserting holidays, checking for broken meetings, or running the "terminated user" option in our code.

If you do not have a specific service account set up yet, this is a good place to start.

Server-side holiday insertion in Exchange 2007 - example

Well yes, we did go ahead and add the server-side holiday insertion into our mainstream migration code for Exchange 2007.

And we even field-tested it at a site in a mythical place called Canada.

This is a (slightly revised for purposes of pedagogy) holiday file, showing some of the flexibility of our approach. Notice you can have holidays which show as Free "F" or Busy (abbreviation is left as an exercise to the reader) so that our Canadian cousins can list USA holidays as information for everyone in their company, but make sure the time shows as Busy (i.e., do not book then) for Canadian holidays on their calendars.

In an example of instant karma, the test site told us of a wonderfully simple short cut to permissions in setting up insertion (for those of you who have not been through a migration) based on BlackBerry Enterprise Server permissions, which we'll blog on separately.

Please note that this has the following advantages:

• It's run server-side with no user intervention
• It is scriptable from the DOS command line
• It's reversible, i.e., we built in UNDO capability for those occasional accidents
• Handles multiple time zones

Any sites who have been through a migration with us are welcome to use this capability at no charge for Exchange 2007. Just drop us a line if you do not have the latest code.

GeekSpeak: Memory Leaks in System.DirectoryServices

It rained 22 days in June (in Boston). The last few days were glorious. And I missed the sun while dealing with a memory leak.

We hit this problem while translating legacy Exchange DNs into SMTP addresses in our Exchange Room analysis tool. The culprit -- System.DirectorServices (.Net 3.5)
calls to GetDirectoryEntry().Properties. With each call to System.Directoryservices, memory use jumped by 120 bytes. The annoyance became a problem after we looked up three fields - for 8,000 users.

Microsoft's MSDN Reference says: "Due to implementation restrictions, the SearchResultCollection class cannot release all of its unmanaged resources when it is garbage collected. To prevent a memory leak, you must call the Dispose method when the SearchResultCollection object is no longer needed.".

I did that. So did other folks posted similar problems in the MS forums. All were told to use dispose. It didn't work. After reading dozens of responses, someone said try the "using" contruct along with "dispose". I did. It worked.

For those of you who don't want to find the mines by stomping on the ground, here is sample code that shows System.DirectoryServices calls broken out into an excessive number of using blocks:



'return ONE value from AD given a filter
Public Function GetADField(byval strFilter as string, _
 byval strField as string) As String
 GetADField = ""
 Using dsDir As System.DirectoryServices.ActiveDirectory.Domain = _
  System.DirectoryServices.ActiveDirectory.Domain.GetCurrentDomain
    Using dsRoot As New DirectoryEntry(dsDir.Name)
      Using dsSearcher As New DirectoryServices.DirectorySearcher
        dsSearcher.SearchRoot = dsRoot
        dsSearcher.Filter = strFilter
        dsSearcher.SearchScope = SearchScope.Subtree
        dsSearcher.PropertiesToLoad.AddRange(New String() {strField})
        dsSearcher.FindAll() 'results
        Using dsResult As DirectoryServices.SearchResultCollection = _
            dsSearcher.FindAll() 'results
            Dim result As DirectoryServices.SearchResult
            For Each result In dsResult
             Using de As DirectoryEntry = result.GetDirectoryEntry()
               GetADField = de.Properties("mail").Value.ToString
               de.Dispose()
             End Using 'de
           Next 'result
           dsResult.Dispose()
           result = Nothing
        End Using 'dsResult
      dsSearcher.Dispose()
    End Using 'dsSearcher
   dsRoot.Close()
   dsRoot.Dispose()
  End Using 'dsRoot
  dsDir.Dispose()
 End Using 'dsDir
 Return GetADField
End Function

Bulk Move Meeting Maker to Oracle Calendar?

Keeping an eye on keyword searches that bring folks to our site usually has few surprises.

Then last month this one showed up: "bulk move meeting maker oracle calendar" (right in there with "calendar migration oracle to exchange" and "meeting maker exchange calendar convert").

Yes, Oracle does have a process to convert Meeting Maker into Oracle Calendar.

They smartly used the Meeting Maker export DAT format (just as we do - it's independent of operating system so it's the most natural format and live Meeting Maker data is a horror show of complexity).

Sidebar: Turnabout fair play with an "X" to Paul Lynde. That's the same
strategy we use to move data OUT of OCS, using the utilities Oracle provides for moving calendar data between servers.

BUT when we ran the MM to OCS conversion (a ways back when we were figuring out how to convert Oracle Calendar to Exchange), we discovered they had missed several key attributes and in general failed to impress us with their solution (we did try licensing our tech to them but they were not interested). Since their own published report example consists mainly of "Nothing to import" messages, you should be appropriately wary.

Cornell did this nice guide when they migrated out of Meeting Maker into OCS and Penn State apparently moved last year.

If you want a real geek instance of calendar comedy, check out their Troubleshooting Calendar Migration Guide for their Microsoft Exchange migration consisting largely of the equivalent of "Step 2: Discard remainder of killer whale carcass" making success seem as accessible as Larry Ellison's yacht habit.

We are surprised that anybody nowadays is considering leaving one waning calendar-only product for another waning calendar-only product.

If it works for you, that's all the matters.

As always our message is: try it out for yourself beforehand and follow Reagan's maxim of "trust but verify."

But also be prepared to migrate again in a few years.

Double Booking in Exchange 2003? Look to BES Versions

Gentle Reader,

As a blogging calendar geek Ms. Calendars sometimes gets requests from the field. When they are useful to the general calendar-server managing public, she publishes them.

So it has come to pass that a question came in:

You mentioned on your site about the "perennial exchange problem of double-booked meetings". I thought I would drop you a line to see if this qualifies. We have Exchange 2003 and Blackberry Enterprise Server 4.1.3. Our users run Outlook 2003. We get these periods where users claim they are getting double booked meetings. More often than not we see one as tentative and one as accepted in the same time period. Do you have a resource that clearly explains why this happens? Is BES the culprit? Thanks in advance. Rick

Double bookings are really not unusual in Outlook. Microsoft itself has a guide on How to troubleshoot missing and duplicate appointments in Outlook. It is a work of singular genius: wonderfully complete in what could be causing the problem, and mostly silent on solutions or protocols to solutions (in contrast to Russ's latest blog entry), all the while referring you to other links which will hopefully keep you from realizing you are being given the runaround.

Just because we make a good living out of working with Exchange does not mean we're going to drink the Kool-Aid or praise the manure as BBQ.

But it does advise keeping abreast of your software updates, and that did turn out to be the problem.

In the end the problem has been solved by updating to BES version 4.1.6. The release notes go over the brand new BlackBerry Calendar Synchronization Tool. And to see what effect this will have on your Exchange server, see Technical Note: Impact of using the BlackBerry Calendar Synchronization Tool. So keep an eye on your BES servers, folks.

In general, we've noticed pretty big changes going on in CDO on E2K3: see here and here. With two years of E2K7 migrations under our belt, we're encouraging folks to migrate into E2K7 rather than E2K3.

Also, check out Information about CDO patching and third-party programs that interface with the calendar in Exchange Server and in Outlook.

We have another report of calendar weirdness from the field, this one with BES and E2K7, which we are pretty sure is related to the known problems with cached mode and the incremental change system. We'll blog on that later.

In general, if you notice weird behavior on your calendars, start with your BES server and work back from there. BES is the source of most calendar headaches we hear tell of.

Sex Sells....but you still can't print

I attended an MSDN conference this week where I learned more about Silverlight 3. Compared to V2.0 its new features make it slicker:

• 3D graphics are sexier;
• Runs as a desktop app and in the browser;
• Apps run online or offline (and run faster).

Should you consider Silverlight or WPF for your Intranet / Line of Business (LOB) apps? My take:

• Silverlight will make a very Rich Internet App (RIA). BUT you still can't print without a major code hack, and it has basic HTTP binding (no full security).
• If you have existing WinForm apps, WPF may be the better choice (it's a logical extension of your existing platform).
• If you have most of your stuff in ASP.Net, then start with Silverlight (it has a small footprint, produces great cross-platform apps, and is easy to deploy).

Before you blindly walk down the path, figure out what 'features' your end users want, and then figure out which product supports those features. Here are two MSDN blogs that compare the two technologies: Jennifer Marsman (a Microsoft Developer-Evangelist) summarized the differences (although the post is a year old); The Swiss MSDN Team updates it for Silverlight 3.

Free/Busy not working in Outlook 2007 (Exchange 2007)

Zyg interrupted my Friday development meeting and asked why a client could not see Free/Busy in Outlook 2007, but saw F/B in OWA. He drops this on us without even bribing us with coffee and bagels. Someone says the Exchange Availability service has problems. But that makes no sense. OWA uses the availability service (pointing directly at the CAS servers). Outlook 2007 does too. Well sort of. It uses the autodiscover to find the availability service. I bet autodiscover was not correctly configured. I was wrong - it was DNS. Here is how we figured it out:

Use Outlook 'Test E-mail Autoconfiguration'
Outlook 2007 has a tool "Test E-mail Autoconfiguration" to identify the current autodiscover URLs. You can find this tool by launching Outlook 2007, then holding the Ctrl key and right-clicking on the Outlook icon in the system tray while clicking your heels together. In the form, enter an email address and password, uncheck Use Guessmart and Secure Guessmart Authentication and click Test. We looked at the log tab and saw AutoDiscover is failing -


or there was a problem with the autodiscover URL. The errors 0x800C8203 and 0x80072EE7 pointed to DNS - either DNS did not resolve the name or there was no web server at that URL. (We hope it's just a name resolution.) We checked by configuring logging in Outlook: Tools, Options, Other, Advanced, Check logging. We restarted outlook, opened a meeting, then refreshed free busy. (BTW, remember to turn off logging after you are done!) We saw:


Fix the problem in DNS

DNS. Ugh. I’d rather talk to my teenagers about sex, drugs, and the merits of doing their homework than wrestle with DNS. But the problem was simple - add a Forward Lookup Zone, then add a CNAME record. We used “DNSmgmt” (Start-Administrative Tools – DNS)

Forward Lookup Zone: Right-click on your existing forward lookup zone and select a New Zone. A wizard will walk you through the steps. The goal is to redirect ‘autodiscover.domain’ to ‘servername.domain’. You do this in five steps:

1. Select Primary zone for the zone type;


2. Store the zone in Active Directory


3. Set the replication to all DNS servers in AD (this is just for internal requests)


4. Enter the FULL NAME, e.g. autodiscover.ex2007.sumatra.local


5. Allow both nonsecure and secure dynamic updates (this minimizes the possibility of Exchange giving you a hard time should you resign your Certificate.)

Create a new CNAME: Right-hand click on your newly created autodiscover zone and select New CNAME

1. Browse the fully qualified domain name, traverse the DNS tree, and look for the Host (A) record in the DNS (e.g., it might be (same as parent folder).


2. We did not add a name to the CNAME record. Click OK and you are done.


3. Wait a few minutes until the DNS changes are sent throughout the organization.

And that worked.

Oracle Calendar Migration: International Characters

As Roseanne Roseannadanna said, it's always something.

The European calendar migration business has been picking up for us lately, and Oracle Calendar is the main thing folks want to get out of. Oracle Calendar is where Meeting Maker was five years ago, but they have a larger installed base and even more irate users (Beehive did not help things).

So let's look at Jerry's calendar with this entry, a mix of German and Spanish.


Using our standard export tool on the OCS side, UNICPOUTU, this exports as:

K Events:

S 9691980

D 30

T Du mußt Amboß oder Hammer sein, Señor

I 0

R N2

M Garcia Jerry

W Garcia Jerry

A TRUE 3 10O

Which is perfectly fine.

It comes into our database correctly as:

And will insert into Exchange just as you see.

So we're pretty sure we're covered here.

But, we've had some reports of some UNICPOUTU exports not including accented characters (and they're translated to reasonable substitutions so we know something is going on). The Oracle Admin Guide section on Calendar International Support goes into fair detail on how to configure for all your various options. As always, when in doubt, check with us. We want to take as much information to your target system as accurately as possible.

Sensitive to some of the other options that might be coming down the pike, we've added a new character set option to our conversion code:

So in case we need to do Japanese or some other non-European character set we'll be able to respond.

This means the OraCalReader also has a new command line switch: /CHARSET whose values values can currently be "UTF" and "ASCII."

One additional note: Time Zones. We've been handling European and Asia-Pac time zones in OCS to Exchange migrations for years. No worries.

Script to automate Oracle Calendar Server exports

Thanks to Marco Siefert, KUTTIG GmbH, Germany for this script that he's just used on a migration from OCS to Exchange right now. It would work just as well of course for exporting in an Oracle Calendar to Zimbra migration.

No matter what I do in blogger, the indentations get screwy so I'm also putting this in the next round of migration documentation.

#!/bin/sh export CAL_HOME=/opt/oracle/OraOcs10gHome/ocal/bin #Set allowpasswordoption = TRUE in [UTL] section of unison.ini of OCS calendar $CAL_HOME/uniuser -ls -format "%s%:%g%:%uid%:%id%:%node-id%:" -n 1 -p sysoppassword > users.txt $CAL_HOME/uniuser -resource -ls "S=*" -n 1 -p sysoppassword> resources.txt while read mylinedo #Replacing spaces with % so it can be passed to awk str=$myline str=${str/\ /%} #Declaring variables surname="" givenname="" uid="" startch=":" endch=":" #Launching export command with awk echo sysoppassword awk -v str=$str -v st=$startch -v end=$endch 'BEGIN{ if (length(str)>0){ system("echo Processing line "str) #Cutting variables out of the line s=index(str,startch) e=index(str,end) givenname=substr(str,s,e-1) surname=substr(str,e+1) uid=surname surname=substr(surname,0,index(surname,":")-1) uid=substr(uid,index(uid,":")+1) uid=substr(uid,0,index(uid,":")-1) #Replacing % in uid for unicpoutu tool, not replacing it in givenname because that is used in the export filename gsub("%"," ",uid) system("echo UID="uid) #When we have a givenname then start with export if (length(givenname) > 0) system("$CAL_HOME/unicpoutu -u \"UID="uid"\" -f exp-"surname"-"givenname".txt -n 1") } else system("echo ---------------------------------------") }' done <>

Reference our earlier posts on exporting data from Oracle Calendar. For example, How to Extract Data from Oracle Calendar Server for a migration into Exchange or Zimbra.

In the script the value for CAL_HOME and sysoppassword have to be replaced before running.

To provide a password to unicpoutu change the config file "unison.ini" before exporting (can be found in $CAL_HOME\ocal\misc). The line allpasswordoption = TRUE should be added to the [UTL] section.

Exchange 2007 Rollup 8 for SP1

MS released Exchange 2007 Rollup 8 for SP1 last week. The KnowledgeBase http://support.microsoft.com/kb/968012 reports four calendar fixes:

• 966535 Duplicate messages are sent to an external recipient if the recipient is included in multiple distribution lists in an Exchange Server 2007 environment
• 967097 Users may receive duplicate calendar items for the updated instance on mobile devices
• 967109 delegate cannot accept a meeting request for an online meeting in an Exchange Server 2007 environment
  

Oracle Calendar Migration: ICS vs UNICPOUTU

We've been asked why we don't just migrate out of Oracle Calendar using ICS format.

We could, but the results are way better using UNICPOUTU.

Let's look at Jimi Hendrix's meeting with Jerry Garcia and John Lennon in ICS format. The meeting title is "Jimi, Jerry, John"


You'll notice that any of the recurrence pattern syntax is absent, as is any concept of the meeting ATTENDEES. Yes, you can take this and you can insert it as is into Exchange or any other calendar system that reads iCalendar. BUT without recurrences, attendees (and therefore attendee response status) and with no connection to managed conference rooms or resources.

It is very easy to insert this way -- but it is also less functional when it arrives at the target system. Users will need to add back all their guests and send invitations, which the guests then need to respond to. And don't forget the great conference room land grab that's going to happen the second your people get wind the conference rooms are not yet booked on the new system.

And let's look at the same meeting in UNICPOUTU export, Oracle Calendar's own format.

It is CRUCIALLY better because while we are (still) lacking the recurrence patterns (don't worry, we re-create those), we have the attendee list and the attendee responses! This means we can re-create the full state of the meeting and make it live in Exchange. This also allows us to re-create the status in conference rooms.

Yes, this means in a system like Exchange that we need to re-propose the meetings and respond to them. But the results at the end are much more seamless and require less user interaction to get back to its previous state. After doing this for almost nine years though we think we've gotten good at it.

Name changes and calendar behavior in Exchange 2007

This might seem a little esoteric, but it's still important.

Let's look at name changes in Exchange / Active Directory and how they have an impact on calendaring.

User Name Changes has done a good job of sketching out the mechanics of name changes and its repercussions for email. However, as with anything else there's some consequences for calendars that we feel the need to document.

So let's look at Marge Bouvier and her calendar in Exchange 2007.


In the way of many marriages, Marge changes her name to Simpson after marrying her high school sweetheart, Orenthal.

If we change her name (leaving her alias alone) and go back into her calendar we note that the display name at the top is "Marge Simpson." New meetings are created as "Marge Simpson" but previously created meetings are still labeled "Marge Bouvier."



What happens when previously existing meetings are modified?

So glad you asked.

In her GUESTs' calendars (for example Russ) the original meeting looks like this:

If Marge updates it (say by adding an agenda), the invitation comes into Russ's inbox looking like it's from Marge Simpson:


But accepting it and looking at it in Russ's calendar, it will STILL identify the organizer as "Bouvier."

SO NOW, let's look at it the other way: When the organizer modifies a meeting Marge is a guest in.

Say, Russ modifies his original meeting:



Like this:

MARGE sees the following update come into her inbox (identifying her as Marge Simpson):


And now this exception is listed in Russ's calendar as having Marge Simpson as a guest.

Confused?

If you're not confused you haven't been paying close attention.

The situation is at least comprehensible because updates are at least still going between Marge and everybody else in the organization. What makes this possible is that her Alias ("marge") remained constant. Meetings which are unchanged keep her as "Marge Bouvier" meetings which are new or get updated list her as "Marge Simpson" (most of the time).

If her alias started as "marge.bouvier" and it needed to morph to "marge.simpson" things would be a lot wilder and woollier with all previous meetings now invalid and updates being impossible (exactly as happens with email in this situation).

I leave as an exercise to the interested reader what happens to any Delegate rights Marge had set up prior to her name change.

True Conference Room Anecdote

So I was having lunch a few weeks ago with two people, let's call them Bill and Kelly, who were stalwarts of the Meeting Maker world back when.

Not surprisingly the talk turned to calendaring.

Kelly was telling me how her non-profit Boston office has two conference rooms, and one being necessary for an auditor for an extended period of time, lots of non-software interpersonal skills (what someone outside of psych-speak would call "peer pressure" or "bribery" or possibly "extortion") were brought to bear to free up the conference room.

It's as we tell you: The most important things to consider in your calendar system or migration are the inanimate objects. People will do anything for conference rooms.

Server-Side Exchange 2007 Holiday Insertion

OK. We know you keep asking for it.

The Sumatra Utilities has had this sort of weird cult following (and we mean weird -- we're not sure we want to meet some of the people who send us email) for its ability to insert holidays server-side on Exchange. But based on CDO it was restricted to Exchange 2003 (and those daring Luddites with a 2000 fixation).

Since the E2K7 code was wide-open for ResourceWatch development, Russ's team just kinda, sorta, threw in the holiday insert. So Memorial Day on my calendar went in server-side via an improved holiday CSV.

And since the code is based on the migration tool we have options to tag "(Migrated)", which was how I actually did it the first time before I went "D'Oh!":

So in answer to the questions we always get:

• Yes, we're now automatically inserting our own Keyword so it's easier to undo (for those of you who ignore our advice by inserting on your production server without an isolated test).
• No, you can't use an existing .hol file. We actually have more capability than the .hol files allow.
• Yes, if you still want to do this client-side there are plenty of directions online, like Customize the Outlook calendar with your company's important HR dates
• Yes, we added the capability to do a "Stockholder's Meeting" on June 30, 2009 from 12:00 noon to 3:00 PM in ALL Calendars server-side.
• Yes, we're field testing it with a few folks now.
• No, we haven't decided if it's going to be a give-away. We're leaning towards bundling it.

Is there anybody out there? In a word: No.

So our article Corporate Microsoft Exchange to Google Calendar migrations: Is there anybody out there? generated lots of feedback -- all of it confidential.

We're used to this by now.

But here are the high-level conclusions:

• CORPORATE Google Calendar? Fuggedaboutit. Does not exist at the enterprise level. Actually it doesn't seem to exist in business beyond the "Mom and Pop started this store and needed some calendaring" level. There is one exception in Europe via an SAP consultancy we're too curious to let drop.
• Educational: Sure - but we've been put off by free not being a viable business model for us.

So don't wait up for us to do a full state calendar migration from Exchange / Oracle Calendar / Meeting Maker to Google.

Preview of ResourceWatch

We thought we'd give you a taste of something that's been in development and now in beta. We've been doing analysis of resource use in Exchange for a while, and when one of our favorite clients in the world asked us about turning our analysis into something they could use on an on-going basis, we kind of just started writing it.

Since pictures are worth more than words, I'll start the screen grabs here.

That's the screen display, based on Silverlight. We just all love the way the data comes up on the screen.

But since Microsoft believes Silverlight has no need to ever print anything, we have a separate portion handling output (we call it the "Printer-friendly version"), and these are representative samples:

So what the heck can you do with this? Well you can finally

• Have statistics on how often conference rooms / resources are used
• Know how many people have used them
• See when the high demand days / times are
• Start to quantify decisions like "Do I need two conference rooms on this floor or will one do?"

Broken E2K7 Meetings Part 2: Getting rid of them.

So you have some broken meetings, eh?

It's easy for your users to just delete them -- but your conference rooms have a certain inflexible uncreative temperament that means some biological entity capable of passing the Turing test needs to be looking over their collective shoulders.

Or you could use software.

Specifically our software.

First let's revisit the broken meetings in Conference Room 222 of our previous post. The 10:00 AM meeting is broken, and should not be in the calendar.

How do we have the audacity to call it "broken?"

Well it's not in the owner's calendar, and he tried to cancel it. I'd argue it's pretty clear it should not be in the resource calendar.

So now we probably want to divide this into two steps: Finding the broken meetings and removing the broken meetings.

Those of you with experience with SuExchange2007 will be aware of the little "test" button in the corner. This is where we send you to test that you really do have adequate permissions for the calendar insertion we're about to do.


This is also where we're headed to get this menu:

I've taken the liberty of filling in Conference Room 222's alias: "room222" and indicating that it is a resource.

Now, click this button:

And it will create a text file called "_suExLog_BrokenMtgs.txt" which includes our test subject:

Pressing "Delete Broken Meetings" will remove them and log that to a report.

This is scriptable so if you're interested let us know.

Sorry, folks, this one only works for Exchange 2007.
