Some update on my challenge to get around organising things. Apparently it wasn't the fault of Evolution per se to be unable to connect to the exchange server. It seems to be a problem in Fedora Core 5. My notebook with Ubuntu connects without any problem. Mail, Calendar, Tasks and Memos work nicely. I have yet to validate this. Ubuntu is running Evolution 2.2 and Fedora something 2.5.xx ... which in itself should indicate that it is not a final release.

The unofficial but very good Ubuntu User Guide

Mhh, I didn't realize that FireFox has a 4k limit on strings in its JavaScript implementation. How on earth can you use that browser for AJaX stuff. Just little neaty strings can be transmitted, or what?

Seems to be a known problem, Text node maximum size.
