You need to create an OpenLDAP server which Thunderbird, Evolution, Mac Mail, even Outlook (with a plugin) can connect to. If you want to go the whole hog you'll need an ical server using Webdav too if you want to replace all of Exchange with Open source variants, then Postfix, Courier IMAP for all the mail functionality, something like roundcube or squirrelmail for the equivalent of OWA and Yaa! to do out of office replies. Its all do, just need a nice frontend to tie them all together!
