PropertySet propertiesAll = new PropertySet(BasePropertySet.IdOnly, ... , AppointmentSchema.TimeZone, AppointmentSchema.StartTimeZone, ...);
ServiceResponseCollectionresponse = Exchange.LoadPropertiesForItems(items, propertiesAll);
But not Appointment.StartTimeZone returns null.
Appointment.TimeZone is a string, which seems to be equivalent to the DisplayName of the TimeZoneInfo object, but unfortunately, this seems to be the language of the end user (in our environment, I have encountered the difference that Exchange returns for different appointments Language). Therefore, it seems complicated/impossible to use the TimeZone string correctly for appointments.
The main question is, what could cause the StartTimeZone of the appointment to be null?
Sorry, I don’t have any help
I can retrieve the Appointment.TimeZone of the project:

ServiceResponseCollectionresponse = Exchange.LoadPropertiesForItems(items, propertiesAll);

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