EWS 일정 당 안내 저장 약속

Question

모든 약속마다 안내를 저장해야합니다.

, 내가 PolicyTag 및 ArchiveTag를 사용하는 것을 시도했다, 그러나 얻었다 "속성 PolicyTag은 Exchange Exchange2013 또는 이후 버전에 유효합니다."

예외입니다.

Exchange 2010과 비슷한 점이 있습니까? 자체 생성 ID가 포함 된 appointment.ID이 있다는 것을 알고 있습니다. 나는 그것을 사용하지 않는 것을 선호한다. 감사합니다.

이 문제를 해결하기위한 방법은 확장 속성을 생성하고, 약속 GUID를 넣어, 당신은 다른 약속의 복사본을 만든 않는 한

private static readonly PropertyDefinitionBase AppointementIdPropertyDefinition = new ExtendedPropertyDefinition(DefaultExtendedPropertySet.PublicStrings, "AppointmentID", MapiPropertyType.String); 
public static PropertySet PropertySet = new PropertySet(BasePropertySet.FirstClassProperties, AppointementIdPropertyDefinition); 


//Setting the property for the appointment 
public static void SetGuidForAppointement(Appointment appointment) 
{ 
    try 
    { 
     appointment.SetExtendedProperty((ExtendedPropertyDefinition)AppointementIdPropertyDefinition, Guid.NewGuid().ToString()); 
     appointment.Update(ConflictResolutionMode.AlwaysOverwrite, SendInvitationsOrCancellationsMode.SendToNone); 
    } 
    catch (Exception ex) 
    { 
     // logging the exception 
    } 
} 

//Getting the property for the appointment 
public static string GetGuidForAppointement(Appointment appointment) 
{ 
    var result = ""; 
    try 
    { 
     appointment.Load(PropertySet); 
     foreach (var extendedProperty in appointment.ExtendedProperties) 
     { 
      if (extendedProperty.PropertyDefinition.Name == "AppointmentID") 
      { 
       result = extendedProperty.Value.ToString(); 
      } 
     } 
    } 
    catch (Exception ex) 
    { 
    // logging the exception 
    } 
    return result; 
} 

(결국 그냥 속성입니다) 변경 실 거예요

이 솔루션은 단일 약속의 경우와 온 프레미스 Exchange를 사용하는 경우에 매우 효과적입니다. 여기서 문제는 Office 365와 같은 OWA (Online Web Access)의 모임의 경우 약속의 속성이 주최자의 원래 약속에서 복사 된 것이며 이러한 속성 중 AppoinmentID가 포함 된 확장 속성입니다 . 따라서이 문제를 피하기 위해 주최자의 약속 ID를 주최자의 오리지널 ID와 유사하게 만들고 서비스 소유자 (알림을 생성 한 서비스)의 전자 메일 주소를 추가하기 만합니다. 이 솔루션을 사용하지 않으면 내부 시스템의 약속이 원래 예약과 비슷한 AppointmentID를 가지게되어 하나의 ID로 간주되거나 동일한 ID로 서로 다른 두 개의 약속을 가질 수 있습니다.
