We recently replaced an old exchange server (srv1) with a new exchange server (srv2). So the host names have changed.
Migration was fine and mail flow works as expected, however the issue we have is that all internal outlook clients (2003/xp) are still trying to connect to old exchange hostname (srv1). So when you open outlook a login box pops up prompting for credentials and has the old hostname which is no longer online and we are having to manually update the settings for each client.
If we create a new user and connect it to outlook it pulls the proper server and autodiscover connectivity tests from the microsoft connectivity tool come back fine.
My question is: How can we either make the new server (srv2) answer requests for the old one, (srv1); or make it so that the clients automatically start going to srv2?
