Outport aims to be a generic program for exporting data from Outlook to various email/pim programs. Currently it can export to the Contact, Calendar and Task formats of Evolution, plus a number of generic formats supported by Outlook itself (Rich Text Format, HTML, vCalendar, vCard, iCalendar, etc).
I've tested this with Outlook 2000 and most releases of Evolution 1. 0. x and 1. 2. x. I have not tested this with any other version of Outlook. I've received some reports of success with Outlook XP (and some bugs).
