256986 Description of the Microsoft Windows Registry
Microsoft Exchange 2000 Server Service Pack 2 (SP2) contains a new diagnostic feature that provides support for "per-user tracing." Per-user tracing is a facility for tracing activity on the server for a specified mailbox or user. This feature can only be enabled on retail builds.

WARNING: If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use Registry Editor at your own risk.
To enable this feature, you need to create or set the following registry values under the following registry key on the Exchange 2000 server:
as type reg_sz. In addition, specific users need to be identified for tracing. The registry value
Trace User LegacyDN
needs to be set to the legacy Exchange Distinguished Name (DN) of the user for which tracing will be enabled. For example:
Trace User LegacyDN=/o=OrgName/ou=SiteName/cn=Recipients/cn=1234
Collectively, these registry settings will enable tracing for the specified mailbox. In addition, the delegate logons to the user mailbox will also be traced. To disable filtered tracing, Enable Tracing must be set to 0 and the Trace User LegacyDN registry value should also be removed.
The following is an example of a registry file that can be constructed to enable tracing on a user's mailbox:
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\MSExchangeIS\ParametersSystem] "Enable Tracing"=dword:00000001 "Trace User LegacyDN"="/o=OrgName/ou=SiteName/cn=Recipients/cn=1234"
