Outlook 03 Re-boots machine

[brettban]

One of our users has numerous mail folders set-up in OL2003, when they try to move an e-mail from one folder to another, the machine instantly freezes and re-boots. Any ideas what might be causing this? The client computer is running Win XP Pro SP2, Outlook 2003 SP1, server is Small Business Server 2003 with Exchange server running. I've built a different profile - same problem. I also setup Outlook with the same user settings and mailbox on a different computer - same problem on that computer. The moving between folders is under exchange inbox and not other pst folders. I was wondering - could the files be corrupt on the exchange server? Is there way to re-build the user’s exchange files on the server? Also, this user has many sub-folders under his inbox - probably 20-30 folders - could this be a problem? His data files exceed 150MB...thanks for any help or insight.
