SUMMARY
=======

When Microsoft Exchange Mailbox Manager performs the cleanup, you may see
several 1016 events similar to the following in the event log:

  1016
  NT User ExchService logged on to ExUser1 mailbox, and is not the Primary
  Windows NT Account on this mailbox.

MORE INFORMATION
================

This is by design. An event with the ID 1016 is logged when you attempt to
access another user's mailbox or schedule. Mailbox Manager does not disable this
security logging.
