Emails don't appear in Inbox until user opens another folder

[Mannstech]

Hi,

This is a very trivial problem but when a new mail is sent to any of our users running the email doesn't actually show in the Inbox unless they are in a different folder (e.g. Sent Items, Deleted etc. etc) or if they click on another folder and then click back into the Inbox. We are running Exchange Server within Small Business Server 2000.

Anyone any ideas why this might be happening and what can be done to rectify the (minor) problem?

Many thanks.

Are they past a firewall that might be blocking UDP traffic?

Thanks for the reply... Yes, all traffic is passing through a firewall but UDP traffic doesn't seem to be blocked...

Any suggestions gratefully received!

This problem happens after installing Windows XP SP2.

Yep - it's almost always a firewall issue that does that. The new mail notifications are UDP based.
