we used to have exchange server A (5.5), it went down couple times. so, i added a new exch srv B (5.5) to the site. Then, i moved mailboxes from A to B. Everybody is fine except for one person. sometimes (not all the time), when he tried to send mail, he got error: "Task 'Microsoft Exchange Server - Receiving' reported error (0x8004010F): 'The operation failed. An object could not be found."
i take a look on MS, it said that Exch svr couldn't find Offline Address Book. i couldn't find Offline Address Book on our servers. can you guys help me out?
