Just wondering if there's an open source Linux alternative to MS
Exchange so that all the features of outlook work?
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.
