Attendee.ResponseType未知 - Exchange託管API

Question

我試圖獲取作爲預約所需參與者的房間的ResponseType時出現問題。我可以確認我的Exchange 2010 sp2 ru4服務器即時批准或拒絕會議，但是當我通過ExchangeManaged api編程發現約會時，所需的與會者始終會爲ResponseType返回「未知」值。

這裏是我的代碼...

public bool IsAppointmentVerifiedWithResource(Patron userSessionObj, Reservation reservation) 
    { 
     var emailConfig = new DataStoreManager.ConfigurationManager(); 
     var serviceBinding = emailConfig.GetConfiguration(Configuration.GetConfigurationName(Resource_ConfigurationConstants.ExchangeServiceBinding)); 

     // Create the binding. 
     var service = new ExchangeService(ExchangeVersion.Exchange2010_SP2) 
     { 
      UseDefaultCredentials = true, 
      Url = new Uri(serviceBinding) 
     }; 

     // Set the calendar view to use 
     var view = new CalendarView(reservation.Start, reservation.End); 

     // Get the target folder ID using the email address 
     var folder = new FolderId(WellKnownFolderName.Calendar, new Mailbox(reservation.EmailAddress)); 

     view.PropertySet = new PropertySet(BasePropertySet.FirstClassProperties); 

     if (CheckForApptCount(service, folder, view)) 
     { 
      var response = service.FindAppointments(folder, view); 

      service.LoadPropertiesForItems(from Item item in response select item, BasePropertySet.FirstClassProperties); 

      foreach (Appointment apt in response.Items) 
      { 
       foreach(Attendee at in apt.RequiredAttendees) 
       { 
        //room mailbox matches required attendee 
        if(at.Address == reservation.EmailAddress) 
        { 
         ******at.ResponseType always = Unknown****** 
         if(at.ResponseType == MeetingResponseType.Accept) 
         { 
          return true; 
         } 
        } 
       } 
      } 

     } 

     return false; 

    } 

如何獲得的responseType財產同步和加載任何想法？

謝謝， 克里斯

發現的解決方案：參加者的的responseType總是空，因爲我是做了與會者的郵箱「findappointments」，然後試圖獲得該與會者的responseTyp的。獲取參加者的ResponseType的正確方法是爲組織者的郵箱運行「findappointments」。一旦找到約會，列舉出席者，並且ResponseType將可用。
