[lug] Exchange server without IMAP?

[David Morris]

The company I work for in all its *abundant* stupidity has
decided to disable IMAP access to their email server.

I need to find a way, if possible, to access their exchange
server without using IMAP.  I would prefer a solution that
reads messages directly on the server, but would not mind a
downloading messages if that is what it would take to keep
using a Linux mail client.

Any suggestions?
