using exchange distribution list calendar "view" from Address Book

Hi!

We have a customer that uses each others calendars a lot.
They have now started to report that there is one calendar group they can't open anymore.

I start to see what changes have been done to the system - nothing....
Just some new users so they just passed the 100 users milestone (if you'd like)

The have an Exchange distribution group with 102 users - "All Employees"

Some users (when adding a calendar group) use "open calendar" ->  From Address Book...
They chooses this list since it has all users in it. So they don't need to add every user manually.

The thing is that this stopped working for some reason. When I troubleshoot, I find out that this list now holds 102 users. I removed 2 users, so it was 100 blank. THEN it works.
When I add the 2 excluded users back, the calendar is not expanding. I just get an error message.

Please see Attached file for type of error Message. It's in Norwegian, but here goes the translation:

"Could not open this Group" Contact Microsoft Exchange Server-administrator for more information."

It seems like it is a limit for this on hundred 100 users. anyone knows a workaround or a fix?

we have the fix for opening more simultaneously calendars. It doesn't seem to be affected by this. Cause it is not really opening simultaneously calendars. The real problem is expanding calendar group list. Hope I made my self clear enough :)



Cheers!

There is a limit of 100 calendars open at any one time. That is why you are getting the problem.

This blog post goes on about the problem, and shows that 100 is the largest value you can have.

No work around using native tools. You would have to switch to third party tools instead.
