SYMPTOMS

When a user in a Microsoft Exchange Server 2003 organization performs a Send/Receive operation in Microsoft Outlook, the user may receive the following error message:
Unknown error 0x8004011B
Additionally, one or both of the following events may be recorded in the Application log.

Event ID 9360Event ID: 9360
Category: OAL Generator
Source: MSExchangeSA
Type: Error
Machine: SERVER_NAME
Message: OALGen encountered an error while generating the changes.oab file for version 2 and 3 differential downloads of address list "\Global Address List". The offline address list has not been updated so clients will not be able to download the current set of changes. Check other logged events to find the cause of this error. If the cause of the problem was intentional or cannot be resolved OALGen can be forced to post a full offline address list by creating the DWORD registry key "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\MSExchangeSA\Parameters\OAL post full if diff fails" and setting it to 1 on this server. When OALGen next generates the offline address list clients will perform a full OAB download. After that time the registry key should be removed to prevent further full downloads.

CAUSE
