In preparation for migrating our exchange instance, I looked at event logs to see if there were any major problems. I noticed a couple recurring errors that happen daily. The event IDs are: 9116, 9331, and 9360.
They all point towards the Offline Address Book. My research has been pointing me towards a problem with creating differential downloads and accessing the public folder store while generating the offline address list.
From what I have found online, it sounds like I need to
A. Rebuild the OAB
B. Reg hack so that if it fails to create the differential, it will download the full OAB
C. Maybe a permissions issue to the destination OAB file?
What do you guys/gals think? I am leaning towards A & B.
Thanks!
