The Microsoft® Exchange Server Analyzer Tool queries the Active Directory® directory service to determine whether the messageTrackingEnabled property of the server object is set to TRUE (enabled) or FALSE (disabled).

If the Exchange Server Analyzer determines that the messageTrackingEnabled property of the server object is set to False, the Exchange Server Analyzer displays an error.

The messageTrackingEnabled property of the server object determines the state of the Message Tracking Center for the server.

The Message Tracking Center, when it is enabled, logs information about the sender, the mail message, and the message recipients. Specifically, you can review statistics such as the time the message was sent or received, the message size and priority, and the list of message recipients. You can also log the subject line of e-mail messages. The Message Tracking Center searches for messages such as system messages, public folder messages, and e-mail messages.

You must enable the Message Tracking Center on each server for which you want to track messages. When it is enabled, all messages that are routed through a server are added to the message tracking logs.

The Exchange Server Analyzer requires that message tracking be enabled for it to start its scans.

The following permissions are required to perform this procedure: member of the local administrators group and member of a group that has had the Exchange Administrators role applied at the administrative group level
To enable Message Tracking Center on an Exchange 2003 server
  1. In Exchange System Manager, expand Servers, right-click the server on which you want to enable message tracking, and then click Properties.

  2. On the General tab, select the Enable message tracking check box.

  3. To record the subject of any message sent to, from, or through the server, select the Enable subject logging and display check box.

    If you enable subject logging, you may cause some decrease in performance.
  4. Under Log file maintenance, you can prevent the removal of log files or modify the length of time that the log files are kept. The default period that tracking logs are kept is seven days.

    On servers that process large quantities of mail, the tracking logs grow quickly. Make sure that you have sufficient disk space for the log files and for other services or applications that use this disk.
  5. Click OK or Apply. You do not have to restart services for this change to take effect.
