Debugging an IMAP connection - how?

[Chris G <cl@xxxxxxxx>]

Our MS Exchange server now allows IMAP connections and I want to use
mutt to access it.  I have used mutt before with IMAP so know the
basics.

However I'm having trouble getting it to connect to the Exchange
server, so :-

    Are there any special gotchas when using mutt with Exchange?

    Is there any way to log the connection process so I can see where
    it's failing?

    Any other ideas?

I'm pretty sure I am now set up as an IMAP user on the Exchange server
as last week I was getting an error (using Thunderbird) that was
saying that I didn't exist as a user.  Now I just get a failed login
which implies that I have my password wrong but my password works on
the Exchange webmail login and (as far as I know) that is the same
password.
