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.

How to Create Shared Calendars in Office 365 Part 1, Client-Side

Gentle Calendar-Using Reader,

The team at Sumatra feels it is time to update one of our most popular posts ever, Shared Calendars in Exchange 2007 sp1, for the Cloud Era of Office 365.

There are two methods for doing this:  Client-side and Server-Side.  We're going to deal with each in separate blog posts.

You might think that since we did this for Exchange 2007 in the year 2008 of the Common Era that this should be a simple matter of a few well-pointed clicks in a graphical user interface.  It HAS become easier.

Let's look at Client-Side (i.e., End User-Side) first from the perspective of a user in OWA (the process from Outlook is not exactly the same, but you'll get the idea)

First create a secondary calendar:

Now you need to name it something (In this case: "Zyg's Shared Calendar" it could just as easily be "QA schedule" or "group vacations and travel"):

Now let's Right click on the secondary calendar and select Share Calendar to pick who we want to see it and how much power we want to give them to post or edit things:

Note that we can give Russ the ability to Edit or add things and Jimi only the ability to read what's there.  This is darned useful.

From the Microsoft-generated text in Jimi's invitation it is pretty clear that Redmond expects users to have trouble with this process.

Notice that accepting the invitation automatically lists the shared calendar in Jimi's calendar list AND that Jimi can now see the events the owner has posted:
and while Jimi cannot edit or add to the events, Russ can edit any events (and note that in good social practice he is annotating that it's him doing and mods -- Exchange/Outlook/OWA do not do this for you





Note -- you need to be careful what you put into these calendars because events do NOT show up as BUSY in a free/busy check.  So it is very easy for Zyg to book a meeting at the same time.  Note that below you do NOT see a conflict in the Scheduling Assistant.


Another way of doing this is via Groups (I think of this as "SharePoint Lite"):


You get similar options:


Because of  the license requirements of nickel-and-diming Office 365, you will need both a OneDrive for Business license and an Exchange Online license:

Oracle + Zimbra?

My latest newsletter from Zimbra had the following:


As the referenced Press Release Oracle Gives Partners a Fast Path to Cloud explains: "Zimbra plus the Oracle Cloud means users can start small and grow, or start big and get bigger"

Forget the fact that Zimbra's had its own cloud that's been promising the same thing.

The Zimbra back-end of mySQL (now owned by Oracle) makes this start to look more interesting than it might otherwise seem.

Consider this:  Microsoft has the very successful Exchange and Google has its office suite.

What Oracle has is the obsolete Oracle Calendar and the moribund Oracle Beehive.  

Given that Oracle traditionally cannot stand not having anything in the enterprise that Microsoft and Google already have. are we looking at the first tentative steps towards an acquisition?

OCS / Beehive into Zimbra is doable on your own if you want, but you'll need to be really careful of resources.  If you want to do it the right way and you've at least a few thousand users drop us a line.  We've got a long history taking both Oracle and Zimbra into Exchange (I mean, check out the rest of this blog).
