Message Tracking on the Internet Mail Service

When message tracking is enabled, each component handling mail records its activities in a log maintained by the system attendant on each server. The log becomes a trace of the processing of each message as each component receives, processes, and delivers it to the next component. The tracking logs are stored in \Exchsrvr\Tracking.Log.

For more information on message tracking, see Microsoft Exchange Server Maintenance and Troubleshooting.
