OAL Generator Errors: Event ID 9360
Hi GuysWe have started getting this error in our Exchange 2003 OAL server.Event ID: 9360Type: Error 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. - Offline Address List Couple of questions;i) How can I find out what is causing this?ii) What Outlook versions do version 2, version 3, and version 4 apply to?iii) What's the best way to resolve this?Any help appreciated!Thanks in advance.

Thanks..Question - if we decide to regenerate a new OAB file, I assume the clients will download the full file, rather than any difference in what they have at the moment and the new file, which would cause a large load on the network?
