Exchange 2007 - 2013 Coexistance

Just implementing coexistence I have moved a couple of mailboxes over everything seems ok.

the only issue I seem to be having is remote webmail access.

if I browse and enter credentials for a user who is on the 2013 server everything is fine

if I do the same for a user that still resides on the 2007 server, you can see in the browser its trying to redirect to, but you just get the spinning wheel and no mail is ever shown?

I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

This process should happen automatically. If it is not have you treid to recycle the services on the old Exchange server?

Does this work internally?

Internally works fine it redirects to the old OWA

when you say recycle the services I have done a restart on the server if that helps
You *do* have your legacy address defined on your external DNS server and the legacy address to a different ip address than

we do have a External DNS Entry for but it does point to the same ip address, I assume that's the issue then?
Yes.  You are dealing with a loopback issue where the request is originating from an internal address and  getting nat'ed to an external address; the same external address that you are trying to send the request to.
