I've had good success with using davmail[1] with the exchange server at work. It's still hosted on sourceforge, but some extended/community repositories have it as well (like Arch's AUR). It's Java, so relatively portable and easy to get working. It even works with the calendar! [1] http://davmail.sourceforge.net http://davmail.sourceforge.net
