Hello,


I'm using Outlook Object Model to update an appointment using C#.

I'm having a problem with clearing the recurrence pattern of an appointment
that has attendees.


I create a daily recurring meeting with no end date that starts 1 year ago.

Then I execute the following code on the AppointmentItem

AppointmentItem a;

...

a.ClearRecurrencePattern();
a.Save();

a.Send();


Everything works fine until the Send(), when calling Send() it adds the
recurrence back to the appointment and then sends the notices to the
attendees.

This is the RecurringMaster, and if I just save it, it looks correct, but
the notices don't get sent out.

Does anyone know what is wrong?
