    Yes you can introduce CAS role in your env however you won't be able to get full functionality. It's backward compatible with E2K3

      Exchange 2003 is fully compatible with IE7 and 8, as long as it is patched correctly.
      Therefore I would suggest that you ensure that it has the latest updates for Exchange. Run the Exchange Best Practises tool against the system, it should flag if you have something missing.

      You can use Exchange 2007 CAS servers (there is no "Frontend") with Exchange 2003 mailboxes, but the user will only see the Exchange 2003 OWA.
