when I migrate a mailbox to the new server, the client will be informed to restart the outlook and then autodiscover makes the rest of the job. When I check the server setting, I can see the new GUID of the 1st EX2013 server.
Later I want to use a DAG with 2 or 3 EX2013 servers.
Can I do this later ? What about the Client Access GUID for internal clients ?
Do I have to change this to the DAG name ?
