Dear All,
Recently we have installed exchange 2010 SP1 in our organization. Right now all mailboxes are in exchange 2003 servers. We have moved 10 mailboxes to exchange 2010 servers.
Now the issue is that those ten users are unable to download OAB. They are getting error “Operation is failed” after some time. All client users are on outlook 2007 and 2010.
We have checked each and everything at our end, every setting is fine. Mailbox server is generating the OAB and CAS server having the copy in right place. Only users are unable to pick this from CAS server.
We run Get-OfflineAddressBook command in exchange powershell, it’s showing wrong Originating Server.
We have single forest (Domain:- test.com, Child Domain:- corp.test.com) scenario.
In all OAB, its pointing to child domain in originating server. I think issue is come from that but unable to solve this.
If I am point the exchange 2010 mailbox server to pick the OAB from 2K3 server, its working fine.
