New emails not showing up automatically

[Kerri]

You can receive an e-mail but it doesn't show
automatically in the inbox. If you click to another
folder than it will appear. Same thing when you send an
e-mail, it holds it in the Outbox until you click another
folder and then sends it. Brand new Dell's with Office
2002 on it. Nothing's changed on the server end that I
am aware - Exchange 2000.

Something in your network is blocking the UDP that is used to update
your client. Could be a router or gateway, or maybe interference from a
firewall. Talk to your network admin about what is between you and your
Exchange server.
