Email Appears in Bunches

[Guest]

The environment is Exchange 2000 and Outlook 2000 / XP clients, with no POP
accounts or PST's in effect. Users are complaining the email appears to
arrive in bunches or groups in the inbox, or at least appears at once in
bunches. Also, when the affected clients change the display from inbox to
another
folder and back to inbox, a new group of email might appear. It's like the
emails are there the entire time, but can't be viewed until you refresh the
screen.

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.
