I have setup my Exchange 2013 environment
Moved all the Client access roles to the Exchange 2013 Server
I moved my test mailbox to the Exchange 2013 Mailbox Server
Now when I connect using my IPhone I can add the account. Get all Ticks but when I go to retrieve the mail I get "Cant Get Mail, The Connection to the server failed"
I can use OWA and Outlook anywhere with this account. Works fine on a Domain Computer or a Non Domain Computer. Everything works as it should. Expect the IPhone
If I add a mailbox on the 2007 Server. It works fine
