Use Diagnostic Logging

You can use diagnostic logging to record significant events relating to authentication, connections, and client actions. Diagnostic logging for POP3 is written to the Windows 2000 event log and is set on the server hosting the POP3 virtual server instance. If multiple POP3 virtual servers are added to one Exchange computer, all POP3 virtual servers are logged at the level set on the host server. By default, a logging level of None is selected to log only critical errors.

To set the logging level:

  1. Start System Manager
    on the Start menu, point to Programs, point to Microsoft Exchange, and then click System Manager.
  2. Navigate to a server.
