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). &nbsp;I'm wondering how I could retire that FE box? &nbsp;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?<br />

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