Exchange 2003 OWA and Exchange 2007 OWA Coexistence

tferro999 asked

I have an Exchange 2003 server and an Exchange 2007 server that exist in the same AD forest.  The 2003 box is in one OU and the Exchange 2007 box is in another administrative group with a few other 2007 boxes.

My problem is that now when I try to connect to the OWA for my Exchange 2003 box where 99% of the mailboxes reside, it automatically directs me to my new Exchange 2007 servers OWA and gives me a 403 forbidden error.

How can I get the OWA for Exchange 2003 and Exchange 2007 to coexist?
