I've completed a transition from 2003 to 2007. These are the only errors present in my event logs, generated at 4am when the mailboxmaintenance is run.

I've tried to search via Google, but cannot find a great deal to go on. I do not use the off-line address book. Your help would be much appreciated.

We are receiving the exact same to errors. I checked the replicas for the offline address books and found that there was one for exchange administrative group but not the first administrative group. I added a replica for the first administrative group but I still can't update the offline address book. Any help would be great.
