I've just installed Exchange 2007 on an existing Exchange 2003 environment. There is also an existing OWA 2003. I'm trying to setup OWA on the 2007 server but am having a bit of trouble. I want users to use the same address as before (http://email.domain.com
) to reach it. What do I need to do? I set the External URL in the Client Access properties for OWA 2007 but it's still reaching the old OWA. I have also change my DNS record. Is there something else I need to do? Help a newbie out. Thanks in advanced!
