I just recently migrated from Exchange Server 2003 to 2007. Right now I have both boxes running and connectors between the two setup. I made the changes to our PIX and internally to route the mail to the 2007 box and it is working correctly. When I test the internal OWA (https://mail.server.com/owa
) I go right to the page with no problems. When I try to access it externally I get a "Page not found" errror from IIS, but it is the IIS 6 from the "old" mail server. I have made all the internal DNS changes to point to the 2007 box and mail is flowing through the 2007 box but I can't get external OWA to point at the box! Any ideas on what I am missing?
