I have just taken over an Exchange 5.5 server with SP3 installed. It has a Internet Mail Service connection for SMTP mail. It seems that every email that passes through the IMC is archived into the folder C:\exchsrvr\imcdata\in\archive or C:\exchsrvr\imcdata\out\archive. These folders are getting pretty big and although it is easy to go into these folders and delete the contents, I would like to stop this from happening. Is there a setting somewhere that makes Exchange archive mail? Thanks for any help.
