Blackberry Desktop Manager Problem with Outlook...

I've spent hours on the phone with RIM tech support and they have
gotten me nowhere.  I've got a PC that whenever you try and start the
desktop manager it just hangs at connecting to e-mail system.  If you
start it without a profile it will start fine.  I've done multiple
clean uninstalls, deleted and recreated the profile multiple times,
and even reinstalled office.  (The desktop manager would start without
office installed.)

I'm running Office 2003 with an Exchange 2003 mailbox.  The desktop
manager is version 3.6 SP2.  The last place RIM support left me was to
call Microsoft because it wasn't an issue with their software.  I'm
guessing that it's something with the MAPI system.

Any ideas?

Thanks!
