EWS：在更新系列更新時，設置操作對屬性無效

我正在使用Microsoft的EWS API 1.2.1與Exchange Server 2007 SP1進行通信。當我嘗試更新系列中的特定事件時，我總是得到錯誤：「設置操作對於屬性無效」。下面的示例創建了一個成功的masterrecurrence，然後我綁定到這個masterrecurrence並嘗試更新系列中的第3個序列。這失敗了...EWS：在更新系列更新時，設置操作對屬性無效

this is the stack trace: 

Microsoft.Exchange.WebServices.Data.ServiceResponseException was unhandled 
Message=Set action is invalid for property. 
Source=Microsoft.Exchange.WebServices 
StackTrace: 
    at Microsoft.Exchange.WebServices.Data.ServiceResponse.InternalThrowIfNecessary() 
    at Microsoft.Exchange.WebServices.Data.ServiceResponse.ThrowIfNecessary() 
    at Microsoft.Exchange.WebServices.Data.MultiResponseServiceRequest`1.Execute()

有人可以幫我解決這個問題嗎？提前致謝！！

下面你會發現我設置的完整測試代碼。

謝謝，最好的問候！

我有一個相關的「修飾的發生交叉或重疊的相鄰的發生」錯誤。

我想這是因爲修改後的occurence開始不能在主復發開始（2012-07-13> 2012-07-11）前設置：

app.Start = new DateTime(2012, 7, 13, 10, 0,0); 
... 
occurrence.Start = new DateTime(2012, 7, 11, 14, 0, 0);

改變，要經過：

occurrence.Start = occurrence.Start.AddHours(-6);

一切似乎都在工作。

我想你應該先改變約會開始，然後改變它的第一次出現並刪除最後一次。但我不確定你是否真的想要這樣。只需添加一個不重複的約會就會更容易。
