256986 Description of the Microsoft Windows registry



SYMPTOMS
After you install Microsoft Windows XP Service Pack 2 (SP2), when you try to send a message in Microsoft Outlook, the message is not immediately sent. The message remains in your Outbox folder longer than you expect.



WORKAROUND
To work around this problem, click a folder other than the Outbox folder, or open any e-mail message. This action sends a remote procedure call (RPC) to the Exchange server, and the e-mail messages in your Outbox folder are sent.

You can also configure Outlook to always use remote procedure calls instead of the User Datagram Protocol (UDP). To do this, follow these steps.

Warning Serious problems might occur if you modify the registry incorrectly by using Registry Editor or by using another method. These problems might require that you reinstall your operating system. Microsoft cannot guarantee that these problems can be solved. Modify the registry at your own risk.  Click Start, click Run, type regedit, and then click OK. In Registry Editor, click the following registry subkey:

Note In this subkey, <10.0> represents the version number that corresponds to the version of Outlook that you have installed. For a table of version numbers, see the &quot;More Information&quot; section.

If this subkey does not exist, follow these steps to create it:  Locate and then click the following subkey:

 On the Edit menu, point to New, click Key, type RPC, and then press ENTER.  Right-click RPC, point to New, click Dword Value, type ForcePolling, and then press ENTER.</li> In the right pane, right-click ForcePolling, click Modify, type 1 in the Edit DWORD Value dialog box, and then click OK.</li> Locate and then click the following subkey:

</li> On the Edit menu, point to New, click Key, type Office, and then press ENTER.</li> Right-click Office, point to New, click Key, type the version number that corresponds to the version of Outlook that you have installed, and then press ENTER.</li> Right-click the key that you created in step 7, point to New, click Key, type Outlook, and then press ENTER.</li> Right-click Outlook, point to New, click Key, type RPC, and then press ENTER.</li> Right-click RPC, point to New, click Dword Value, type ForcePolling, and then press ENTER.</li> In the right pane, right-click ForcePolling, click Modify, type 1 in the Edit DWORD Value dialog box, and then click OK.</li> Quit Registry Editor, and then restart the computer.</li></ol>

<div class="moreinformation_section">

MORE INFORMATION
The following version numbers correspond to versions of Microsoft Outlook.

The ForcePolling registry entry determines whether polling is the default behavior for new e-mail notification. A value of 1 indicates that polling is the default behavior in Outlook. UDP is not used. When polling is the default behavior, Outlook sends the server a remote procedure call at set intervals. The remote procedure call requests information about outstanding e-mail messages.

By default, the interval is 60 seconds. The interval is controlled by a registry entry in the following subkey on the Exchange server:

The entry has the following attributes:

Name: Maximum Polling Frequency

Data Type: REG_DWORD

Value: 60000
