In an Exchange 2007 environment that will have only two physical servers, what is the recommended role placement? (The only roles to be implemented are the minimum: mailbox, HT, and CAS).
One server will have the mailbox role.
One server will have the CAS role.
Which server should have the hub transport? Given that there is no clustering or redundancy, is there an advantage to combining the hub transport with one role over the other?
