Outlook for Mac 2011 Client Crashing While trying to access Calendar Permissions

Hello All,

This is an issue I have been dealing with for the past week and I still have not been able to find a solution for it.

What is happening is one of our executives is trying to share his calendar with another employee. Whenever he tries to access the permissions for the calendar the Folder Properties: Calendar dialog box opens then after a few moments Outlook crashes and displays this error:

Microsoft Error Reporting log version: 2.0

When I first saw this happen I believed that it was a client issue, but after further investigation we noticed that while trying to share his calendar within the OWA he also received an error. This leads me to believe that this issue has something to do with his account permissions on the Exchange server, or his account on the exchange server has been corrupted somehow.The Calendar is the only issue. Everything else (Mail, Mail Sharing, Calendar actions besides sharing) all function properly. Also, All other Mailboxes and Outlook Clients have no issues.

We Are running Exchange 2010.

If anyone has any ideas on what may be causing this any help would be greatly appreciated.

Thanks
