e-mails not coming in until a button is pressed

[childofthe1980s]

Hello:

One of my users does not receive new e-mailed messages, until he hits a
folder such as "Sent Items".

It's strange. He will sit there and someone will call him on the phone
telling him that he has a new e-mailed message. But, he does not see the new
message until he presses a "button" or folder in his Outlook such as Sent
Items.

Now, I think someone loaded XP service pack 2 on his workstation. I'm not
sure if that's when the problem developed, but...

Anyway, he doesn't save many e-mails. So, it's not a matter of network
traffic or "clogging". And, his is the only machine on the network that has
this problem.

If you have any ideas, I'd like to know.

Thanks!

The problem you're having is that the information (called "UDP packets")
that Exchange is sending to notify Outlook of changes to your mailbox is
being blocked by something - probably the Windows Internet Connection
Firewall. You can set the registry values in
http://support.microsoft.com/default.aspx?scid=kb;en-us;Q305572 (Outlook
2002) or http://support.microsoft.com/default.aspx?scid=kb;en-us;Q304849
(Outlook 2000) to cause Outlook to poll Exchange rather than waiting for
notifications.
