I have a workstation running XP SP2 and Outlook 2002. Outlook is configured to communicate with an Exchange server. Recently, Outlook has been operating as though the necessary Windows Firewall program exception and registry entry have not been made. New emails do not appear without first clicking on an item in Outlook and items appear to hang in the Outbox, but when you view the Outbox, all the emails have been sent. If I disable the Windows Firewall, Outlook functions normally. I tested to see if the exceptions were not working, but I have an exception enabled for Remote Desktop and it works fine. Normally, the firewall settings are applied via Group Policy, but I have disabled the policy and made the settings at the workstation with the same results. Any thoughts?

Thanks. We'll let you know when a new response is added.

You need to do a couple of things:
1. Put an exception for outlook in the firewall.
2.In the registry, add the following :

[HKEY_CURRENT_USERSoftwarePoliciesMicrosoftOffice10.0OutlookRPC]
“ForcePolling”=dword:00000000

3.In the registry, change the following key:

[HKEY_CURRENT_USERSoftwareMicrosoftOffice10.0OutlookRPC]
“ForcePolling”=dword:00000001
Change to 0

    Thanks for your response. I did not make it clear in my original post. The program exception has been added and the registry entry is in place, but the problem remains.

    Is this an Exchange server 2003 SP2 mail server? Ever since we went to Sp2 I would not say we have had any problems other than it seems to be slower when it comes to send and recieve. I might get an email but till I simply click on the inbox it may not show right away. but it is there. Also I may see that the Outbox shows and Item in it for a couple more seconds than in the past . but when I click the outbox it is empty. I don't know for a Fact but I would assume Microsoft did some changes to cut down on Bandwith use.
