256986 Description of the Microsoft Windows Registry



SYMPTOMS
When you try to send an e-mail message in Microsoft Outlook after you install Microsoft Windows XP Service Pack 2 (SP2), you may find that the e-mail message may remain in your Outbox folder longer than expected.



CAUSE
This issue occurs when the Microsoft Windows Firewall that is automatically enabled in Windows XP SP2 blocks the incoming UDP (Universal Datagram Packets) ports. Therefore, the notification that the e-mail message has been sent from the Microsoft Exchange Server does not reach the user.



RESOLUTION
Use one of the following methods to resolve this issue.

Method 1
Add Outlook to the Windows Firewall exception list. To do this, follow these steps:
 * 1) Click Start, click Control Panel, and then click Security Center.
 * 2) Click Windows Firewall under Manage security settings for area.
 * 3) On the Exceptions tab, click Add Program.
 * 4) In the Add a Program dialog box, click Outlook.

Note If you do not see Outlook in the Add a Program dialog box, click Browse, look for the file in the C:\Program Files\Microsoft Office\ \Outlook folder, and then click Open.

Note that the  placeholder represents the version number of Microsoft Office that you are running.
 * 1) Click OK two times.

Method 2
Configure Outlook to use remote procedure call (RPC) instead of using UDP to receive new e-mail notifications. To do this, configure the ForcePolling value to RPC in the following registry subkey:

MORE INFORMATION
The registry value of 1 indicates that polling is used as the default by Outlook 2002, and that UDP will not be used. The default polling time is 60 seconds, and it is set in the Exchange Server.

 * For Microsoft Outlook 2000, the < > placeholder is the number 9.
 * For Outlook 2002, the < > placeholder is the number 10.
 * For Microsoft Office Outlook 2003, the < > placeholder is the number 11.
