신뢰할 수있는 도메인에 살고 해당 도메인의 Exchange 서버에서 사서함 일정 모음을 모니터링하고 약속을 동기화하는 데 필요한 앱을 작성하고 있습니다. 하나 이상의 다른 서버에있는 다른 사서함으로. 동기화되는 사서함은이 응용 프로그램의 사용자가 관리하는 내부 매핑 테이블 (sqlce)에 정의되어 있습니다.EWS Managed API SyncFolderItems 항목을 업데이트하고 삭제/추적하는 방법
문제는 원격 약속을 추적하여 필요한 경우 업데이트하거나 삭제할 수있는 방법을 찾지 못하는 것입니다. 원격 서버에 약속을 만든 후에는 로컬 Exchange 서버에서 동기화 폴더 항목 호출에 의해 반환 된 것과 일치하지 않는 새 itemid가 있습니다. 항목이 변경되거나 삭제되었을 수 있으므로 시작 시간/제목별로 항목을 찾을 수 없습니다.
내 동기화 방법이 아래에 있습니다. 전적으로 잘못된 방식일까요? 아니면 SyncFolderItems 메서드를 사용하는 더 좋은 방법이 있습니까?
내가 지금까지 내 문제를 해결하기 위해 내놓았던 가장 좋은 방법은 원격 약속의 ItemID를 로컬 약속의 속성으로 저장하는 것입니다. 그러나 이것도 내가 모르기 때문에 작동하지 않을 것입니다. 속성은 삭제 후에도 유지됩니까? 도와주세요!
