Exchange Web Services and Property Sets
I need to retrieve calendar information by invoking the Exchange Web Service in BPOS. I'm using a CalendarView with a PropertySet to retrieve as little data as possible. However, property sets seems to be limited. I need the EmailAddress of the one who made the calendar appointment so I thought I could use the AppointmentSchema.Organizer in the PropertySet.
When fetching a whole appointment I can get the e-mail through appt.Organizer.EmailAddress. But with the code below the Organizer.EmailAddress is always null. I've enabled the trace and checked it and only the Organizer.Name property is sent, nothing else. Does anyone have a solution on how to get the EmailAddress when using a PropertySet?
CalendarView view = new CalendarView(dtFrom, dtTo);
view.PropertySet = new PropertySet(ItemSchema.Subject);
view.PropertySet.Add(ItemSchema.Id);
view.PropertySet.Add(AppointmentSchema.Start);
view.PropertySet.Add(AppointmentSchema.End);
view.PropertySet.Add(AppointmentSchema.Organizer); // This should contain EmailAddress but it doesn't
Mailbox mailbox = new Mailbox("[email protected]");
FolderId id = new FolderId(WellKnownFolderName.Calendar, mailbox);
CalendarFolder folder = CalendarFolder.Bind(service, id);
FindItemsResults<Appointment> findResults = folder.FindAppointments(view);
Answer
This should work (does for me):
service.FindAppointments(WellKnownFolderName.Calendar, new CalendarView(start, end)).Where(s => DateTime.Now < s.Start);
service.LoadPropertiesForItems(appointments, PropertySet.FirstClassProperties);
