In a com add-in, is there a way to programatically test whether an
appointmentItem object is a series master, or just an occurrence in
the series? I found that the IsRecurring property is True, whether or
not the item is the master. And I don't see anything like an IsMaster
or IsOccurrence property.

Is there a way to do this?

Thanks,
John
