Outlook 2003 Reminder

[Scot]

We just finished upgrading to Exchange 2003 and suddenly
the Outlook 2003 clients (we have Outlook 97, 2000, and a
few 2003 clients) do not have pop-up reminders. I have
tried virtually all the /CleanReminders and other
switches suggested on the Support Pages for Microsoft,
but none have worked. I have also removed and added my
Outlook profile, however, that has not worked either.
The other 97 and 2000 clients function fine once you
removed and added the profiles.

Any suggestions?

Thank you.
