I have just started getting this (since yesterday, 2010-03-10). I have been using mutt to connect to a microsoft exchange server via secure imap for about a year without a problem and now this has suddenly started. I lose mutt about every 5 mins. As with Marco this means I can no longer use mutt. I have checked with the admin who runs the exchange server and he says that he has not changed anything on the server side.
