Hi All, I am am wondering if anyone can help me on this. This is the scenario : 2 Exchange Servers in two different physical locations (Different subnets) – let’s call them EXCH1 and EXCH2 Both set up with DAG All mailboxes are homed on EXCH1 as shown by the command “Get-Mailbox” EXCH1 either dies/loses power/there is a complete loss of connectivity to that server. Now as a result of all mailboxes being homed on that server none of the clients can send or receive email even though EXCH2 is available. The Database has been activated on EXCH2. Even if clients restart outlook, outlook just hangs. (Using outlook 2007) Question: How do I force all the mailboxes that were homed on EXCH1 to now be homed on EXCH2 WITHOUT having to do a New Local Move to another database on EXCH2 (It is not possible to do a Local Move to the same database name even though it is now active on a different server) I have tried ldifde by extracting the users data and changing the homeMTA and msExchHomeServerName attributes and importing them back in (which they do change and are shown as changed when doing a “Get-Mailbox”) but outlook STILL tries to connect to the old EXCH1 server and therefore no mail works. Hope you can help me out on this.

I have fixed it. The problem is the default CAS Server. Just need to run : Set-MailboxDatabase <DataBase Name> -RpcClientAccessServer <Server Name>
