The Ximian Connector for Microsoft Exchange allows Ximian Evolution clients to access accounts on Microsoft Exchange 2000 servers. It is available through Ximian Red Carpet in its own channel or through novell's website. See the product's site for more details: https://store.ximian.com/xproddetail.php?sku=XCN14-DL-U01.
Unlike the regular Ximian Evolution client, the Ximian Connector for Microsoft Exchange is proprietary software and source code is not available.

Thanks, Andrew! Actually, the connector has, in fact, recently been GPL'ed. This happened a few months ago, thanks to Novell. Details about this can be found in the Evolution 2.0 press release from Novell.
Re: Evolution works with Exchange 2000
I loaded this on my laptop in October and have been using it on the exchange server at work. It works well having this since tool since we have alot of Linux and Unix boxes. We can access anything from Linux including the ability to remote into Microsoft servers (2000 & 2003).
