Looks like Novell GPL’ed the Ximian Connector for hooking Evolution up to Exchange 2000/2003. Panu Matilainen was nice enough to start working on a spec for building RPMs from the Source. See his posting to the Fedora Test Archives Below.
I’ve successfully built the RPM but unfortunately, I don’t have an Exchange 2000/2003 Server to test against yet. I’ll let you know when I can get an account on an Exchange 2003 server.
