Whenever I receive a meeting cancellation request from this one user, Outlook hangs until it generates the "encountered a problem and must close error", restarts.
I can accept meeting requests from this user fine, and they are added to my calendar, yet if she were to cancel that meeting, hang ....
Email received is fine
Other users meeting cancellations are removed OK as well
