EWS：在更新系列更新时，设置操作对属性无效

我正在使用Microsoft的EWS API 1.2.1与Exchange Server 2007 SP1进行通信。当我尝试更新系列中的特定事件时，我总是得到错误：“设置操作对于属性无效”。下面的示例创建了一个成功的masterrecurrence，然后我绑定到这个masterrecurrence并尝试更新系列中的第3个序列。这失败了...EWS：在更新系列更新时，设置操作对属性无效

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()

有人可以帮我解决这个问题吗？提前致谢！！

下面你会发现我设置的完整测试代码。

谢谢，最好的问候！

我有一个相关的“修饰的发生交叉或重叠的相邻的发生”错误。

我想这是因为修改后的occurence开始不能在主复发开始（2012-07-13> 2012-07-11）前设置：

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

改变，要经过：

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

一切似乎都在工作。

我想你应该先改变约会开始，然后改变它的第一次出现并删除最后一次。但我不确定你是否真的想要这样。只需添加一个不重复的约会就会更容易。
