We have Exchange 2003 SP2, this is an Outlook 2003 SP2 client. I have my own mailbox, a PST file and another mailbox (support inbox that I monitor) set up in my profile. Came in this morning, started up Outlook, my both Exchange mailboxes appear twice - the .pst file once. This has happened twice so far. Deleting my profile and recreating it removes the duplicate inboxes, but that's going to get a little old. My coworker also has run into the same problem. I am a domain admin, local admin on the machine, Windows XP Pro SP2 and latest updates. Any help or ideas would be appreciated! - Mike
