Mailbox Not Closed Properly

[divins]

I have multiple people in my company that, many times during the week, each
time they open up Outlook, they get the message that their mailbox was not
closed properly. It then takes anywhere from 5-30 minutes to scan the
mailbox for issues before eventually opening up Outlook. We are running
Exchange 2003 SP2.
Each user is using Outlook 2003 SP3 in cached mode.
I have tried to delete the OST and recreate it. That seems to resolve the
issues for a few weeks and then the issue comes back again. I've disabled
windows search, copernica, google search, xobni on the laptops as I have read
that sometimes these applications have a lock on the OST file even after
outlook is closed.

Most of these individuals have very large mailboxes, in excess of 2GB in
size, and some of those have very large folder structure with a lot of nested
folders.

I'm not sure where to go from here. Could it be our AntiVirus that is
causing the problem? Should I exclude the OST file from the AV scanner?

Any help would be much appreciated.

AV is a possibility; try to exempt AV scanning from a few users to confirm.

Another possibility is that users shut down Windows without closing
Outlook first. Even if they do, make sure that outlook.exe does no
longer show in the Task Manager's Processes tab.

Does the same thing also happen if users start Outlook in Safe Mode
(Start | Run | outlook.exe /safe)?

Thanks for the reply. I'll have them do this tomorrow and i'll reply back
with what happens.
