Problem with IMAP against MS Exchange 2007

[Bjørn-Helge Mevik]

At work, they have just started using an MS Exchange 2007 as mail
server, and now I cannot get my mail in Gnus.

I'm using Gnus 5.10.8 in GNU Emacs 21.3.1 under Redhat EL WS 4 on a Dell
x86_64 computer.

I am able to read and send mail with Thunderbird, using IMAP with SSL
against the Exchange server, but would prefer to continue using Gnus.

When starting gnus, I get several messages like "6 BAD The specified
message set is invalid.", and finally "Process imap not running".  See
the contents of the .gnus.el file, the *Messages* and *imap-log*
buffers below.


Does anyone know what is wrong, and how I can fix it?



********************************

Here is my .gnus.el file (I used almost exactly the same settings
against the old IMAP server (not an MS Exchange server), and it worked
like a charm):

********************************
;; IMAP related settings:

;; Degub imap:
(setq imap-log t)
(setq
 gnus-select-method '(nnimap "umb"
                             (nnimap-address "exch01.ans.umb.no")
                             (nnimap-stream ssl)
                             (nnimap-authenticator login)
                             )
 )

;; Probably irrellevant settings:
(add-hook 'gnus-group-mode-hook 'gnus-topic-mode)
(setq gnus-group-line-format "%m%M%S%p%P%5y: %(%G%)\n"
      gnus-permanently-visible-groups "nnfolder\\|nnml\\|nnimap")
(add-hook 'gnus-summary-mode-hook 'bhm-alter-summary-map)
(defun bhm-alter-summary-map ()
  (local-set-key "E" 'gnus-summary-put-mark-as-expirable-next))
(setq user-mail-address "bjorn-helge.mevik@umb.no"
      user-full-name "Bjørn-Helge Mevik"
)
(setq
 nnmail-use-long-file-names t
 nnmail-cache-accepted-message-ids t
 mm-verify-option 'known
 mm-decrypt-option 'known
 gnus-buttonized-mime-types '("multipart/signed" "multipart/encrypted")
 mm-text-html-renderer 'html2text
 mm-discouraged-alternatives '("text/html" "text/richtext")
)
********************************

Here is the (relevant part of the) *Messages* buffer after M-x gnus:

********************************

And here is the contents of the *imap-log* buffer (username and
password have been masked, and "^M"s have been stripped):
