Our exchange 2003 server is in our root domain and we migrated all of our users and workstation to a child domain. The issue we are having since the migration is that if you create a user account in the child domain then attempt to setup Outlook the client can't seem to connect to the server. But if (and this has become our practice now) we migrate the user to the root domain we can setup Outlook with no problems. Then we move them back to the child domain and Outlook works like a charm. Has anyone seen this kind of behavior before? What should I do to resolve this annoying issue. I'm not sure if this is an Exchange 2003 problem or an AD specifit issue. Thanks
