The hardware of our exchange 2010 server was dying and for that reason we installed a new exchange 2010 ( with all the roles ), mailboxes have been moved and everything seemed fine until I decided to turn off the old server for testing purposes.
Unfortunately test went wrong and the outlook of all users got disconnected and kept promting for password.
I ran a " test email autoconfiguration " on one of the outlook clients i found that outlook still connects to the old server ( see attached ).
What i dont get is why outlook doesnt connect to the new server which has all the roles installed ( cas, hub, mailbox ), even thought all mailboxes are on the new server already.
Any ideas ?
