I recently migrated my Exchange 2003 server to Exchange 2010. It went smoothly with the exception of some offline address book issues. I got those straightened out after having to recreate the virtual directory in IIS and a few other things. But it now functions cleanly on all clients (Outlook 2003 - 2010).
The problem is the server is now producing a warning for event 9341 and 9116 saying users need to download the full address book every time instead of a differential. The language of the error is:
The parent Legacy Exchange DN container value '/o=ExchangeOrg1/ou=Old2003AdminGroup/cn=Recipients/cn=Users' was not found during generation of the differential update file for offline address list '\Global Address List'. This will force clients using this offline address list to do a full download of the offline address list.
- \Default Offline Address List
As you can see, it is looking at the old administrative group and not the one with Exchange 2010 in it. Although all new users on 2010 are showing up in the OAB.
Any thoughts on getting rid of this?
