How to Set Logging at the Debug Level for the SMTP Protocol

 

Topic Last Modified: 2006-11-16

If you are experiencing mail flow issues and want to view all events, you can modify a registry key to set logging to the highest level (field engineering level 7).

noteNote:
Incorrectly editing the registry can cause serious problems that may require you to reinstall your operating system. Problems resulting from editing the registry incorrectly may not be able to be resolved. Before editing the registry, back up any valuable data.

Before you perform the procedure in this topic, read Troubleshooting Mail Flow and SMTP.

The following permissions are required to perform this procedure:

  • Member of the local administrators group and a member of a group that has had the Exchange Administrators role applied at the administrative group level

  1. Start Registry Editor: From the Start menu, click Run, and then type regedit.

  2. In Registry Editor, locate and right-click the following registry key value, and then click Edit:

    HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\ MSExchangeTransport\Diagnostics\SMTP Protocol

  3. Set the value to 7.
