Zimbra 5.0.9 server and client.
In outlook, open other users folder (Inbox).

Inbox loads, can view emails.

Shared permissions are Admin, so I should be able to do anything to the messages in the inbox.

Now I delete a message from the inbox, and outlook crashes.

Also, if I copy a message from my inbox to the shared inbox outlook crashes.

Odd thing is, the delete (or move) actually happens, and the results can be seen on restarting outlook, or in the webclient.
