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，我总是会收到错误消息：“设置操作对属性无效”。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三个序列。这失败了...

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！！

您可以在下面找到我设置的完整测试代码。

谢谢和最好的问候！

我有一个相关的“修改后的事件是交叉或重叠相邻事件”错误。

我认为这是因为不能在主循环开始之前设置修改的发生开始（2012-07-13 > 2012-07-11）：

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

将其更改为：

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

一切似乎都在工作。

我认为您应该先更改约会开始，然后更改它的第一次出现并删除最后一个。但我不确定你是否真的想要那样。只添加一个非经常性约会会更容易。
