Duplicate entries in Exchange 2010 calendar

Hello everyone,

Here is the scenario:

-Exchange Server 2010 SP3, RU7
-One user affected
-User client is Outlook for Mac 2011
-There are 2 iOS devices connected to user's mailbox via ActiveSync
-One secretary has Editor rights to this mailbox
-Two other user in the same office has Reviewer access to the user's mailbox
-The user does NOT modify or delete the calendar entries, he sometimes creates entries from his iPad/iPhone
-None of users mentioned above use Cached Mode

The problem:  
The calendar entries duplicate randomly, and not all of them at the same time.  It might be only few today and then tomorrow another few or none.  

I don't think is a magic bullet for this problem but I would like to know if other have the same issue and how they approach the problem, where should we start .  We suspect this is a Mac issue but we cannot say that for sure

Thank you for your time spend reading and hopefully replying to my message

Cheers

I have seen issues where using iPhones or other MAC products duplicating calendar items and also not properly updating them. I have seen this with Exchange 2007 and Exchange 2010. For 2007 specifically there was a RU that needed to be applied to resolve a bunch of calendar issues with 3rd party devices.

Is this the only user that has a MAC?

Hi Will,

No, unfortunately no, there are quite  a  few Mac users,  maybe around 15% of the workforce

Do you know if the issue related only to re-occurring calendar items?

No, the issue is not related to re-occurring only, it happens to singular entries too
That is the problem, is hard to find the root cause...

Yes, Troubleshooting calendar issues is difficult and tricky when you have multiple handheld devices,  having a delegate and non-Microsoft OS.
