SYMPTOMS
On a computer that is running Microsoft Exchange Server 2003 and that has more than one logical processor, you may find that Active Directory updates from Exchange 2003 no longer work correctly. The Recipient Update Service does not configure all the Exchange attributes for the user accounts. As a result, these users may not appear in the Global Address List or may not be able to connect to their Exchange mailboxes. Additionally, you may find that event ID 8331 error messages that are similar to the following are repeatedly logged to the application event log: Type: Error

Source: MSExchangeAL

Category: Address List Synchronization

Event ID: 8331

Description:

The service threw an unexpected exception which was caught at Drive:\Titanium\Dsa\Src\Lra\Abv_dg\Lservagent.cpp(4511)

You may also receive event ID 8331 error messages that contain a description that reports than an unexpected exception occurred in the Active Directory Connector (Adc.exe) and in the Lotus Notes Dirsynch Connector component (Addxa.dll).

When you click Check Name while configuring Exchange e-mail accounts in Microsoft Outlook, you may receive an error message that is similar to the following:

The name could not be resolved. The name could not be matched to a name in the address list.
