Diagnostic logging levels determine which Exchange events are
written to the Windows 2000 application event log. You can set
logging levels to provide information with four levels of detail.
The logging level determines which events are written to the event
log. When Exchange generates an event less than or equal to the
logging level, the event is logged.
Events range from significant events (such as application
failures), to moderately important events (such as the receipt of
messages across a gateway), to events relevant only to debugging.

diagnostics logging enables you to change the logging levels to
capture more events in greater detail.
