EWS | Powershell：加載日歷項擴展屬性

Question

我正在嘗試將擴展屬性集加載到其他日歷約會對象中，以報告和操作它們。 但是，我一直對此感到困擾。 每當到達需要加載擴展屬性的行時，都會出現以下錯誤：“ 異常調用” Load“，帶有” 1“參數：”無法使用屬性標簽指定自定義屬性“。GUID和ID /名稱組合必須改為使用 “

我遇到的問題是： $ apApointment.Load（$ psPropset）;

整個代碼如下。 任何幫助表示贊賞。 順便說一句，我仍然是EWS的初學者。 謝謝

Answer 1

問題是您定義了$dispidApptTZDefStartDisplay和$dispidApptTZDefEndDisplay的兩個屬性。 您已使用0x8000范圍內的常量屬性標記值定義了它們。 該范圍內的MAPI標記被命名為屬性，並且它們的實際標記值未設置（它們在郵箱之間變化）。 您需要根據屬性集GUID和屬性ID定義它們。

您擁有的值實際上是屬性ID值，而不是標簽值。 因此，您需要將它們與屬性集GUID結合使用以使它們起作用。 托管API實際上為這些屬性所屬的Appointment屬性集定義了一個常量，因此您可以將這些行更改為：

$dispidApptTZDefStartDisplay = new-object Microsoft.Exchange.WebServices.Data.ExtendedPropertyDefinition([Microsoft.Exchange.WebServices.Data.DefaultExtendedPropertySet]::Appointment, 0x825E,[Microsoft.Exchange.WebServices.Data.MapiPropertyType]::Binary)
$dispidApptTZDefEndDisplay = new-object Microsoft.Exchange.WebServices.Data.ExtendedPropertyDefinition([Microsoft.Exchange.WebServices.Data.DefaultExtendedPropertySet]::Appointment, 0x825F,[Microsoft.Exchange.WebServices.Data.MapiPropertyType]::Binary)

並且它應該清除該錯誤（除非我使Powershell語法令人厭煩：）
