Hello, 

We relocated our AD and Exchange 2007 server  to a new office. All Win 7 domain-joint clients are connecting to Exchange just fine. The issue we are experiencing is that all the non-windows(iPhones, iMacs, and Andoriod)devices cann't connect to Exchange when they are on the LAN but when they are outside the LAN- connecting from the outside the firewall- they are able to connect to Exchange.

Here is the result of one of the tests I ran:
