I've worked in environments with MS Exchange as an internal mail server, using qmail and others as relays, for extra security. The MS server required specialized expertise and compatible clients, MAPI being strongly preferred by Exchange. This has been a PITA for users with free software operating systems. As a last resort, there is an IMAP connector in MS Exchange, but this software functions poorly as an IMAP server. I would suggest a free-software mail server, with support for MAPI, Active Sync and the likes, it there really is a need for it (consider IMAP with idle support and open alternatives for synchronization of PIM data). Look for the likes of Open-Xchange, SoGo, Zarafa, Zimbra for full Exchange compatibility. HTH, -- mișu
