Can't retrieve Appointment.StartTimeZone through EWS Managed API on Exchange 2007 SP1

Question

I can retrieve the Appointment.TimeZone for items with:

PropertySet propertiesAll = new PropertySet(BasePropertySet.IdOnly, ..., AppointmentSche         


        

Answer 1

Unfortunately, Exchange 2007 SP1 does not support the StartTimeZone property of EWS. If you want to use that property, you must use Exchange 2010.

Sorry I couldn't be of any more help
