I'm migrating Exchange 2007 to Exchange 2013 using http://msexchangeguru.com/2013/05/10/exchange2013-migration/
as a guide. I'm at step 8. I'm trying to get OWA and Active-Sync for the 2007 server to redirect through the 2013 server. When I change the NAT to point to the 2013 server, OWA for a 2013 user works fine, but when I log on as a 2007 user I get a blank page.
I have added legacy to the certificate. I setup an internal DNS for the public domain, pointing mail and autodiscover to the 2013 server, and legacy to the 2007 server.
What am i missing here?
