Weird problem in our office, sporadically. We have Exchange 5.5 on Windows
2000, users running Outlook 2003 or Outlook 2000. Has happened with both
versions. With Outlook open, they show no new mail. Then they click on
another folder (i.e. they had Sent Items showing, and clicked on Inbox. Or
in Inbox, clicked on Deleted), and suddenly several new messages appear in
the inbox, some up to an hour old. It's like Outlook isn't getting the new
info from Exchange. Any idea what would cause this, or how to fix it? I
know it's kind of vague, but thought maybe somebody had seen this before.
All users are running XP, all configured the same way. Problem comes and
goes.

Something in your network is blocking UDP packets getting from your
Exchange server to the Outlook client. See
http://support.microsoft.com/default.aspx?scid=kb;en-us;305572 for an
example cause. You'll have to change Outlook to switch to its polling
method until you correct the UDP blockage on your network.
