The adding of a birthday reminder to the calendar is going on behind the
scenes whenever I set the birthday on a contact.  I never told Outlook to do
it.  Since Outlook doesn't retract the original, it leaves a duplicate.  If
you change someone's birthday, Outlook creates a new reminder on the new
date, but leaves the old reminder on the old date.  You really can't trust
the reminders you see until you confirm the birth date listed on the
contact.

I'd like to turn off the automatic birthday reminders feature, and I'd like
to remove the already generated reminders from my contact.
