Can an Exchange 2003 user access thier mailbox by hitting an Exchange 2007 CAS Server?

Helllo,

We have an Exchange 2003 Front End box today for OWA, however, we just stood up two Exchange 2007 Servers (one mailbox and one consolidated CAS/Hub Transport).  I'm wondering how I could retire that FE box?  Is it possible for users who have mailboxes on 2003 to be able to hit the 2007 CAS server for OWA and access thier mailbox?

Thanks

Yes, an Exchange 2007 CAS can act as a proxy for an Exchange 2003 Back-end mailbox server. See the section on "Between an Exchange 2007 Client Access Server and an Exchange Server 2003 Back-end server" at http://msexchangeteam.com/archive/2007/09/04/446918.aspx for further details.

The rule is to always ensure your front-end or CAS is running at least the same version of Exchange - if not better - than the mailbox servers it is proxying requests to. Provided that is true, you are able to work in this sort of setup.
