Email not being received until clicking on an email in the inbox

[Guest]

Why would my incoming email messages no longer appear automatically, but I
must click on another email message first? As soon as I click on another
item in the inbox, my new messages appear.

I assume you have an Exchange server? If so, 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.
