Tracing has been enabled on the Microsoft Exchange Information Store service for all users

[This topic is intended to address a specific issue called out by the Exchange Server Analyzer Tool. You should apply it only to systems that have had the Exchange Server Analyzer Tool run against them and are experiencing that specific issue. The Exchange Server Analyzer Tool, available as a free download, remotely collects configuration data from each server in the topology and automatically analyzes the data. The resulting report details important configuration issues, potential problems, and nondefault product settings. By following these recommendations, you can achieve better performance, scalability, reliability, and uptime. For more information about the tool or to download the latest versions, see "Microsoft Exchange Analyzers" at http://go.microsoft.com/fwlink/?linkid=34707.]

The Microsoft® Exchange Server Analyzer Tool reads the registry to determine whether the Enable Tracing entry is present under:

HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\MSexchangeIS\ParametersSystem

If the Exchange Server Analyzer finds the Enable Tracing registry value present and configured, a warning is displayed.

The Enable Tracing DWORD registry value enables tracing for the Microsoft Exchange Information Store service. Tracing is used in troubleshooting store startup issues and can severely affect performance. Unless you are troubleshooting a problem, this registry setting should not be used. Tracing can be enabled for specific users by adding the Trace User LegacyDN registry string value. If this value is not present, it means that tracing is enabled for all users.

If troubleshooting is not being performed on the Exchange Server computer, this value should not be present.
