Did you have a look at zarafa? Most part of it is open source; the 
outlook connector ist closed source however and requires a license fee 
for more than three clients.
It uses MAPI to connect to Outlook, unlike many other solutions that do 
calendar syncs etc. via the ActiveSync protocol. Zarafa is a completely 
different thing than dovecot, however; it stores all mails in a MySQL 
database.
