Whenever someone sends me a meeting request, my calendar automatically sets
it as a recurring appointment. I know it's not the sender who's setting this
option because I had someone send me a test meeting request, and they
intentionally didn't set it to recur.  When I accepted, it was put on my
calendar as a recurring appointment.  It's such a pain to constantly remove
recurrence.  How can I stop my calendar from automatically setting recurrence
on all appointments?
