I'm trying to setup a new Exchange 2010 server into an existing 2003 environment. I'm using the self signed certificate to test internal access to Exchange and running into problems. When I try to connect to the default site I get the expected certificate probelm and continue to the website, I get the Welcome to IIS7 page. Then if I use the /OWA site it comes up with the expected cert problem / continue, then I get a Windows domain login screen (not the OWA login screen) after a valid UN/PW the page shows "Your request couldn't be completed because no server with the correct security settings was found to handle the request". Any ideas would be appreciated.
