  I recently upgraded MDaemon to the lastest version 26.0.0 and outlook connector 8.0.3 and users are experiencing an issue with replying to messages.  They are receiving a bounceback saying Recipient unknown.  Seems to be adding a GUID type string infront of the email address when replying.

  

   

  Thanks,

  Check the copy of the message in the user's sent items folder.  When the message was sent, what addresses was the message sent to?  You may need to click on the contacts listed to see the actual email address that was used.  

  When Outlook is used with multiple accounts you can end up with with multipe contacts for the same person and in some cases a GUID is stored in the email address field instead of an actual email address.
