I have a MAC X user who is connecting to an Exchange 5.5 server. She is one of 44 users in our organization that connects this way. She is the only one who has this problem where some emails that come into her mailbox are duplicated. These emails are coming from a variety of senders. Her other problem is when her emails are saved to her sent items, it saves the email without any recipients or so she can't reference emails via people she sent to.
We have done the following:
1. Uninstall then Reinstall Entourage. Duplicate emails occur again as well as the same problem in sent items.
2. Delete all instances of duplicate emails, then more duplicate emails re-occur.
I am not a MAC expert but very comfortable on the Windows-Exchange side. PLEASE HELP as this user has been having this issue for a while.
