So, here's the situation. I've been happily using the Evolution email/calendar software with Ubuntu GNU/Linux for several Ubuntu releases for some time now. Of course, this was with the MS Exchange 2003 that my workplace uses. No problem, using the exchange connector plugin for Evolution.
Earlier this year we were upgraded to Exchange 2007, whereupon everything changed - I was no longer able to access the mailserver or calendar. Aha! I thought, I'll find an appropriate plugin for Evolution. Well, that was a little easier to say than achieve. Firstly, many websites refer to an apparently now unavailable plugin named Brutus. Secondly, after I identified the plugin to use (evolution-mapi), it didn't seem to work.
