TimeZone change to UTC while updating the Appointment

Question

I am using EWS 1.2 to send appointments. On creating new Appointments, TimeZone is showing properly on notification mail, but on updating the same appointment, it\'s TimeZon

Answer 1

You'll want to set AppointmentSchema.StartTimeZone and bind it as part of the properties object when you bind existingAppointment, as illustrated here:

// Get an existing calendar item, requesting the Id, Start, and 
//  StartTimeZone properties.
PropertySet props = new PropertySet(
      AppointmentSchema.Id, 
      AppointmentSchema.Start, 
      AppointmentSchema.StartTimeZone);
Appointment appt = Appointment.Bind(service, new ItemId("AQMkA="), props);

It seems the default bound time zone is UTC.
