How are you intending these users access the exchange server? MAPI client

Yes, the clients will use POP/SMTP, IMAP and MAPI. That was my point

IMHO, you'd be better protected using a bastion host outside the firewall.
Internet/bastion host <-> Firewall <-> Users/Exchange

your Exchange servers

On top of that, you may want to propose this sort of scenario for maximum

Internet <> Firewall <> Exchange Front End Server <> Firewall <> Desktops
and Exchange Back
So you don't *really* have AV then, do you? :)
