   Free and open source, and has most of the things you want from Exchange, including shared calendars.

   No Exchange alternative and no support for MS Outlook Client

   Not an Exchange alternative at all. Does basic AD but that is about it. It is more of a gateway server.

   They do not share any common functionality. Zentyal is an Active Directory substitute, Microsoft Exchange is a groupware E-Mail (enterprise grade) server.
