Reading exchange email with mutt and davmail?

I must have read about 65 web pages about this issue, and tried them all, but so far I can't get it to work. I can access my exchange email using Thunderbird, with the imap server set to localhost at port 1143, and the smtp server again set to localhost; this time with port 1025. These port values are set in my davmail setup, and as I say this is what I use with Thunderbird. The relevant portion of my .muttrc file is set realname = 'Jim Bloggs' set imap_user = 'AD\12345' set imap_pass = 'My Password' set from = 'Jim.Bloggs@jimsmail.org' # REMOTE FOLDERS set folder = 'imap://12345@localhost:1143/Inbox' set spoolfile ='imap://12345@localhost:1143/' set trash = 'imap://12345@localhost:1143/Trash' # LOCAL FOLDERS FOR CACHED HEADERS AND CERTIFICATES set header_cache =~/.mutt/jim_bloggs/cache/headers set message_cachedir =~/.mutt/jim_bloggs/cache/bodies set certificate_file =~/.mutt/jim_bloggs/certificates # SMTP SETTINGS set smtp_url = 'smtp://12345@localhost:1025/' set ssl_starttls=yes set smtp_pass = 'My Password' # use the same password as for IMAP Currently what happen is this: it logs in and starts to download mail (and takes a v..e..r..y long time - about 15 or 20 minutes - to download 1902 headers), and then hangs on Sorting mailbox... I am using mutt quite happily for accessing several gmail accounts, and I would like to use it to access my exchange mail as well. But how...?
