Я пытаюсь обновить существующую встречу, но EWS выбрасывает "Set action is invalid for property.". Я проверил все значения, установленные для объекта назначения, но не могу выяснить фактическую причину этой ошибки.
Вот мой фрагмент кода:
ExchangeService service = new ExchangeService(ExchangeVersion.Exchange2010_SP1);
service.Credentials = new WebCredentials("ews_calendar", PASSWORD, "acme");
service.Url = new Uri("https://acme.com/EWS/Exchange.asmx");
ImpersonatedUserId impUser = new ImpersonatedUserId();
service.ImpersonatedUserId = new ImpersonatedUserId(ConnectingIdType.SmtpAddress, "tin.tin@acme.com");
string itemId = "";
DateTime PreviousStartDate = new DateTime(2012, 04, 02, 18, 00, 00);
DateTime PreviousEndDate = new DateTime(2012, 04, 02, 18, 30, 00);
CalendarView calView = new CalendarView(PreviousStartDate, PreviousEndDate);
Appointment appointment = new Appointment(service);
try
{
calView.PropertySet = new PropertySet(BasePropertySet.IdOnly, AppointmentSchema.Subject, AppointmentSchema.Start, AppointmentSchema.IsRecurring, AppointmentSchema.AppointmentType);
FindItemsResults<Appointment> findResults = service.FindAppointments(WellKnownFolderName.Calendar, calView);
List<Item> items = new List<Item>();
foreach (Appointment appt in findResults.Items)
{
appt.Load();
items.Add(appt);
}
if (items.Count > 0)
{
service.LoadPropertiesForItems(items, PropertySet.FirstClassProperties);
appointment = (Appointment) items[0];
appointment.Load(new PropertySet(BasePropertySet.IdOnly, AppointmentSchema.Start, AppointmentSchema.ReminderDueBy, AppointmentSchema.End, AppointmentSchema.StartTimeZone, AppointmentSchema.EndTimeZone, AppointmentSchema.TimeZone));
}
appointment.RequiredAttendees.Add("tin.tin@acme.com");
appointment.Start = new DateTime(2012, 04, 02, 18, 00, 0);
appointment.End = new DateTime(2012, 04, 02, 18, 30, 0);
// throwing exception here -- Set action is invalid for property.
appointment.Update(ConflictResolutionMode.AlwaysOverwrite, SendInvitationsOrCancellationsMode.SendToAllAndSaveCopy);
}
catch (Exception ex)
{
//
}
[ОБНОВЛЕНИЕ]
Интересно, если я прокомментирую RequiredAttendees свойство назначения в приведенном выше коде, все выглядит нормально, но уведомление об этом не отправляется существующим посетителям.
[ОБНОВЛЕНИЕ] Это происходит только для встреч, созданных с помощью iCal
