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:
Additionally, one or both of the following events may be recorded in the Application log.
Event ID 9360
Event 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.
Event ID 9331
Event ID: 9331
Category: OAL Generator
Source: MSExchangeSA
Type: Error
Machine: SERVER_NAME
Message: OALGen encountered error 8004011b (internal ID 5020114) accessing the public folder store while generating the offline address list for address list '\Global Address List'. - Default Offline Address List
Note These events are logged only if diagnostic logging for the OAL Generator category in the MSExchangeSA service is set to the maximum logging level in the Exchange System Manager.
CAUSE
This issue may occur if an error occurs when Exchange Server 2003 generates changes to the .oab file. If this error occurs, Outlook may not download the Offline Address Book.
