Exchange Error 0X8004010F - The Operation failed. An Object could not be found
Funny isn't it? Exchange errors are like buses. Nothing for ages and ages and then 2 come along at the same time. I was doing a Q&A for an customer in Education yesterday. They have lots of schools in their care, and were upgrading from Exchange 5.5 to Exchange 2003. They were concerned about the usual messaging things, auditing, archiving, directory harvesting, blocking MSN Messenger through the firewall, using LCS 2005 for archiving and they had this error 0X8004010F whenever they tried to sync the Offline Address list. I answered their question, went back to my desk to an email from David G. about exactly the same thing. Obviously worthy of a blog entry then.
The error message listed indicates that Outlook was not able to find and download the offline address book. You need to rebuild the OAB.
Open the Exchange System Manager
Drill down and expand the Recipients container object
Select the Offline Address List container object
Right-click the OAB in the right pane then select Rebuild on the context menu
