<p>Hi All,</p><p>I was helping a user delete an undeletable message and saw a number of files with the extension .$M$ in his mailbox directory.  This is a new extension to me and I don't find it in  any Hans' guides.  The file content looks like a .CNM file.  The date stamp range is from 3 months ago to 3 years ago.  Can anyone explain what these are and/or how they come to be?</p><p>Brian Fluet </p>
