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.
So does SOGo, no plugin required for Outlook. There is an extension for
Thunderbird+Lightning, and it also supports most every mobile client out
there.... and it uses Dovecot for the IMAP server *now*, and also
includes OpenChange and Samba4. It is also supposed to be *very*
lightweight, and can integrate with most any other backend you may be
using. We currently use PostfixAdmin for managing email users, and we'll
be able to happily keep using it for as long as we want after the migration.
We will be migrating to SOGo (using Thunderbird+Lightning+Google
Calendar now) very soon, and we are fully expecting to leverage the fact
that SOGo includes Samba4 in the future, so that when the time comes for
another Microsoft Server Upgrade, we will instead 'upgrade' to Samba4,
and demote our older 2008R2 servers to member servers - if we keep them
around at all.
