Oulook hangs, causes ost 'check for errors'...

Hello all,

Here’s my problem:

Outlook 2003 client running on XP Pro in a remote office. Occasionally they
have Outlook hang (outlook didn’t shut down properly…), often times during
folder syncing, upon restarting Outlook it kicks off the long OST repair…
Remote office with a T1, Exchange server (2003) is in my office. Clients are
configured with a cached profile, running Symantec’s corporate AV. These are
corporate executives, kind of large mailboxes so the repair takes a long
time, they also don’t want to delete anything. Mailbox sizes average 4-7
gigs in size.

I’ve remoted to the client machine, I can’t get the thing to hang, I watch
the active processes, Outlook.exe ends every time I close the program. Just
like taking a car to the dealer, just won’t act up when a mechanic is looking
at it.

I’ve tried various fixes, resetting the Outlook toolbar, deleting the
frmcache.lat and outlprnt files. Reregister ole32.dll and inetcomm.dll,
looked at add-ins, don’t see anything unexpected. One client in that office
had itunes, I removed that. Tried resetting the user’s outlook profile, also
have run the ‘repair’ within Outlook. The problem still occasionally
repeats.

Has anyone seen this behavior, and if so, care to share a reason for it?
Better yet, a fix?

Any thoughts would be appreciated.

Thanks,
Ted
