'Traversal' 属性未声明。在 GetItem EWS 请求中

请指教
GetItem元素中没有遍历属性可以查看参考文档https://msdn.microsoft.com/en-us/library/aa563775(v=exchg.150).aspx
遍历仅在 FindItem 和 FindFolder 操作中有效（它指定您正在搜索的文件夹范围）。 GetItem 只是获取您具有其 Id 的特定项目（Id 包含用于定位该项目的信息，因此不需要任何 folder/mailbox 上下文）。这就是说，如果您没有特定项目的权限并且您尝试使用 GetItem，则报告的错误将是商店中不存在该项目（这有点欺骗性）。

您需要开始对您在 Header
中发出的所有 EWS 请求进行版本控制
<soap:Header>
<t:RequestServerVersion Version="Exchange2010_SP2" />
</soap:Header>
您需要输入您使用的架构版本 https://msdn.microsoft.com/en-us/library/office/dn741586(v=exchg.150).aspx（或至少输入 Exchange2007_SP1）。这将解决 EWSId 错误（您将无法使用您尝试使用的 ID，但您应该从其他请求中获得正确的 ID）。
