The following procedure explains how to modify diagnostic logging related to MSExchangeTransport.

Warning

If you increase the logging levels for Exchange services, you will experience some performance degradation. It is recommended that you increase the size of the application log to contain all the data produced. If you do not increase the size of the application log, you will receive frequent reminders that the application log is full.

Procedure

To modify logging settings for MSExchangeTransport

  1. In the console tree, expand Servers, right-click <server name>, and then click Properties.

  2. Click the Diagnostics Logging tab.

  3. Under Services, click MSExchangeTransport.

  4. Under Categories, click the category for which you want to configure the logging level:

    • To troubleshoot routing issues, select Routing Engine/Service. Increase the logging level for this component if messages are accumulating in the Messages waiting to be routed SMTP queue.

    • To troubleshoot problems with address resolution in Active Directory, distribution list expansion, and other categorizer issues, select Categorizer. Increase the logging level for this component if messages are accumulating in the Messages waiting to be routed SMTP queue.

    • To troubleshoot issues with dial-up and virtual private network connectivity through Connection Manager, select Connection Manager.

    • To troubleshoot problems with the queuing engine, select Queuing Engine. Increase the logging level for this component if you are experiencing mail flow problems, and mail is not accumulating in any of the queues.

    • To troubleshoot issues with the Exchange store driver, select Exchange Store Driver. Increase the logging level for this component if messages are accumulating in the local delivery SMTP queue, the X.400 queues, or if you have problems receiving mail from Exchange 5.x servers or other mail systems.

    • To troubleshoot general SMTP issues, select SMTP Protocol. Increase the logging level for this component if messages are accumulating in the Remote delivery SMTP queue to determine if SMTP errors are causing the bottleneck.
