So far only 2 users out of 50 now get Microsoft Exchange Server 2007 reported error (0x8004010f) error message.
Here are a few tech articles about the KB
THIS WAS ONE FIX I READ
After adding a new Exchange 2003 Standard Edition server to an existing Exchange Organization, I recieved the same error message.
"! Task 'Microsoft Exchange Server reported error (0x8004010f): 'The operation failed. An object could not be found.'"
The error was alleviated when I added the new Exchange Server to replication for the "Free/Busy," "OAB Version2," and the "Offline Address Book."
To make this change go to the following location in Exchange System Manager on the Exchange 2003 Server.
Administrative Groups>"Organization Name" >Servers> "Exchange 2003 Server">First Storage Group>Public Folder Store>Public Folder Instances
For each of the following Public Folders ensure that the newly added Exchange Server is added to the "Replication" tab by highlighting the Public Folder Instance, right clicking and selecting "Folder Properties."
None of this is working, does anyone have any suggestions. It will still send and receive it just pops up with this error message.
