TIP
Understanding Default Options
By default, Outlook keeps a list of any assigned tasks, sends status reports when assigned tasks are complete, and sets a reminder for any task for which you enter a due date. You should set these defaults, however, to match your work style. You can always override these options for individual tasks.
