New Zimbra to Office 365 Calendar Migration Version

We've been doing Zimbra to Microsoft Exchange calendar migrations for a while now.

As always -- we mean full-state migrations where meetings come over as real, update-able meetings with all attendees and resources, not just appointment slots in your calendar.

But our previous methods grew out of our first-generation technology using an external database (a legacy of our genesis migrating Meeting Maker).

Our new version reads Zimbra data directly without any intermediate steps or need for tunneling your MySQL ports.  It has the advantages of being simpler and faster but still delivering full calendar migrations.

We'll have more to say about this in January but we've got it going reliably enough for us to tell you about it.

Microsoft Exchange Free/Busy

Good read:  The Hybrid Mesh: why free/busy is broken and what you can do about it.

If you have any external free/busy relationships configured things can get complicated in Exchange.  In truth outside of Exchange they can get almost impossible (props to Zimbra for its efforts on Exchange free/busy integration).

The short answer is that it gets really complicated (basic reason: in email systems where calendaring is an after-thought, free/busy is an after thought to the after thought).

Follow the instructions therein to have any hope of making it work,

Using iTunes to sync contacts on your legacy system and your migration to Exchange

oooohhhh boy.

You think using Apple iTunes on your legacy system (in this case Oracle Beehive) to sync contacts will result in no problems (because Apple has such high quality (yes, this is sarcasm) software in the Windows world.....).  But when you migrate into Exchange some contacts are duplicated.

But you migrate and you get some duplicate contacts.  Not from ALL users, just the ones using iTunes.

Yep.  That happened in a real world site this past weekend.

Use this procdure post-migration to de-dupe:

Delete duplicate contacts

If you imported contacts into Outlook by using the same names or e-mail addresses that already exist in your Contacts folder, and you selected the Allow duplicates to be created option in the Import and Export Wizard, you might have unwanted duplicates of several or all of the contacts that you imported.

Removing the unwanted duplicate contacts is a manual process, but the following is the easiest way to do it.

NOTE:  These instructions are for Outlook 2007. Instructions are also available forOutlook 2013 or Outlook 2010.

In Contacts, select the contacts folder that has duplicate contacts.

In the Navigation Pane, under Current View, click Phone List. This is the best view to scan your contacts list and see the duplicate contacts. Now you can sort the list by modified date and group the duplicates together.

On the View menu, point to Current View, and then click Customize Current View.

Click Fields, select Modified in the Available fields list, and then click Add.

Click Move Up until Modified is at the top of the Show these fields in this order list.

Click OK twice.

In the list of contacts, hold down CTRL while you select each duplicate contact.

When you have selected all the duplicate contacts, press DELETE.

This is from:

How to Create Shared Calendars in Office 365 Part 2, Server-Side

Gentle Reader of Scheduling Intent,

When last we spoke it was of shared calendars / group calendars client-side in Office 365,

Today we will look at the same capability server-side.

In what a psychoanalyst would call a "breakthrough" Microsoft has established a user-interface for an Office 365 Admin to create a Group.  Log in as your Administrator and it is easy to navigate to:

from which

You will need to hit REFRESH (under "More") to see it but you can then add users / owners.

Not bad.

Can you still do this with PowerShell as in the olden days of Exchange 2007?  Sure.  Leave a comment if you'd like to see that.

Oracle calendar to Zimbra via ICS does NOT solve all your problems....

In response to our post: Oracle + Zimbra?  we got at least one person writing in saying "But we can just import the ICS files."

Yes, you can use ICS export/import and it SORT OF works.

You will not have your recurrence patterns and every recurring meeting and appointment will come in as a series of single, disconnected instances.

That is for starters.

Then there are the issues of mapping users throughout the OCS namespace so they map to the new IDs in your Zimbra namespace.

Then there's the issues of conference room / resource behavior that OCS allows but Zimbra does not and how you should deal with that.
