Resolution
Exchange 2000/2003 didn't have CAS servers but they had "Front End" servers.

External clients used the "Front End" as more of a proxy that could handle RPC over HTTP (for Outlook Anywhere), HTTPS (for Outlook Web Access), POP/IMAP
Exchange 2010 introduces a new service (MSExchangeRPC) so that the CAS Role is "true" middle tier
