How to the Outlook Appointment series master from a single occurence

I need to get the master appointment of the meeting series, when an appointment instance is opened.

I have tried the following (currentAppointment variable is of type AppointmentItem)

DateTime sd = currentAppointment.GetRecurrencePattern().PatternStartDate;
DateTime st = currentAppointment.GetRecurrencePattern().StartTime;

AppointmentItem ai = currentAppointment.GetRecurrencePattern().GetOccurrence(sd+st.TimeOfDay);

However, while this gets me the first appointment in the series, it has a RecurrenceState of olApptOccurrence.

How can I get a reference to the olApptMaster - ie the meeting series?

Solution

  • AppointmentItem.Parent will return the parent AppointmentItem for the recurrence instances and exceptions.
