|Message:||OALGen could not generate full details for some entries in the offline address list for address list ‘%1’. To see which entries are affected, event logging for the offline address list generator must be set to at least medium. – %2|
This Warning event is logged when there are problems generating details for one or more entries in an offline address list. The most common cause for this event is when the details information of a user object is larger than the 64-kilobyte (KB) limit. This may occur when a user has many certificates. Because you cannot increase the 64-KB limit, the recommended solution is to remove any unnecessary certificates from the user object in Active Directory.
For details about the cause of this event, configure diagnostic logging on the OAL Generator category of the MSExchangeSA component to Medium or Maximum. Event 9320 may be logged with the following MSExchangeSA Warning and Error events:
Event 9323: Entry %1 has invalid or expired e-mail certificates. These certificates will not be included in the offline address list for %2.
Event 9109: OALGen encountered an error %1 (internal ID %2) while generating address list %3. Check other logged events to see if this is a serious error.
Event 9116: OALGen encountered an error while generating the%1 file for differential downloads of address list %2. Clients will not be able to incrementally update to the new version of the offline address list. This is normal if this is the first time this offline address list has been generated. There is no previous version for clients to start with. Check other logged events to see if this is a serious error.
Event 9321: OALGen could not generate full details for entry %1 in address list %2 because the total size of the details information is greater than 64 kilobytes.
Note The description in Warning event 9321 indicates the user object that exceeds the 64-KB limit
