SYMPTOMS

When you use the JunkMailImportLists registry value to configure Microsoft Office Outlook 2003 to import junk e-mail lists, Outlook 2003 may perform excessive remote procedure call (RPC) requests to update the junk e-mail rule. This may cause poor performance in Outlook 2003. Additionally, you may receive the following error message, where servername is the name of your Microsoft Exchange server:
Outlook is trying to retrieve data from the Microsoft Exchange Server servername

CAUSE

This problem may occur if one or more users in your organization have the following registry data configured on a client computer that is running Outlook 2003:

Registry Key:
HKEY_CURRENT_USER\Software\Policies\Microsoft\Office\11.0\Outlook\Options\Mail

Value Name: JunkMailImportLists
Value Type: REG_DWORD
Value Data: 1

If the JunkMailImportLists registry value is set to 1, Microsoft Outlook imports the junk e-mail list and updates the junk e-mail rule. However, if the JunkMailImportLists registry value is located in the Policies section the registry, the registry value cannot be reset to 0. Therefore, Outlook periodically reads the junk e-mail list and updates the junk e-mail rule. This may cause excessive RPC calls and poor performance in Outlook.

RESOLUTION

This problem was first fixed in a hotfix that is now contained in a service pack. If you installed the latest Office 2003 service pack, you do not have to install the hotfix.

Service pack information

This problem is corrected in Office 2003 Service Pack 2.

To resolve this problem, obtain the latest service pack for Office 2003. For more information, click the following article number to view the article in the Microsoft Knowledge Base:

Hotfix information

How to obtain the hotfix

This issue is fixed in the Microsoft Office Outlook 2003 post-Service Pack 1 Hotfix Package that is dated January 25, 2005. For additional information, click the following article number to view the article in the Microsoft Knowledge Base:
892404 Description of the Outlook 2003 post-Service Pack 1 hotfix package: January 25, 2005


After you install this hotfix, the problem that is described in the "Symptoms" section does not occur regardless of the location of the JunkMailImportLists registry value. If the JunkMailImportList registry value exists and is set to 1, Outlook imports the junk e-mail list only when Outlook starts. The JunkMailImportList registry value is not reset to 0. Therefore, Outlook imports the junk e-mail list every time that Outlook starts unless the JunkMailImportList registry value is set to 0.
