I've recently setup a new Exchange 2010 server, moving fro ma 2003 environment. I have mailboxes on both servers and are currently slowly migrating mailboxes.
With that, I have ran into an issue with the Offline Address Book. Any user who is on the new server is unable to update the OAB - we get 'The operation failed. An object could not be found' along with the a generic error code 0x8004010F.
From what I've read, we need to keep the address book on the EX03 box until all mailboxes are moved. I have not created an OAB on the new 2010 server. BUT! If I open my address book properties in outlook (2010), it is in fact pointing to the new server.
So the, question, how can I point my users on the new 2010 server to my 2003 server? Or can I create a second OAB on the 2010 server and point the clients to that?
