我有 EWS 肥皂请求：

            </m:ItemIds>
        </m:GetItem>
    </soap:Body>
</soap:Envelope>

响应错误是：

                </detail>
            </s:Fault>
        </s:Body>
    </s:Envelope>

为什么会失败？

完美运行

我删除了 traversal 属性，但出现错误：

<?xml version="1.0" encoding="utf-8"?>
<s:Envelope
    xmlns:s="http://schemas.xmlsoap.org/soap/envelope/">
    <s:Body>
        <s:Fault>
            <faultcode
                xmlns:a="http://schemas.microsoft.com/exchange/services/2006/types">a:ErrorSchemaValidation
            </faultcode>
            <faultstring xml:lang="en-US">The request failed schema validation: The 'FieldURI' attribute is invalid - The value 'item:TextBody' is invalid according to its datatype 'http://schemas.microsoft.com/exchange/services/2006/types:UnindexedFieldURIType' - The Enumeration constraint failed.</faultstring>
            <detail>
                <e:ResponseCode
                    xmlns:e="http://schemas.microsoft.com/exchange/services/2006/errors">ErrorSchemaValidation
                </e:ResponseCode>
                <e:Message
                    xmlns:e="http://schemas.microsoft.com/exchange/services/2006/errors">The request failed schema validation.
                </e:Message>
                <t:MessageXml
                    xmlns:t="http://schemas.microsoft.com/exchange/services/2006/types">

                    <t:LinePosition>649</t:LinePosition>
                    <t:Violation>The 'FieldURI' attribute is invalid - The value 'item:TextBody' is invalid according to its datatype 'http://schemas.microsoft.com/exchange/services/2006/types:UnindexedFieldURIType' - The Enumeration constraint failed.</t:Violation>
                </t:MessageXml>
            </detail>
        </s:Fault>
    </s:Body>
</s:Envelope>

然后我删除了最后一个附加属性

 <t:FieldURI FieldURI="item:TextBody"></t:FieldURI>

终于报错了。

【解决方案1】：

GetItem元素中没有traversal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 只是获取您拥有 Id 的特定项目（Id 包含定位项目的信息，因此不需要任何文件夹/邮箱上下文）。也就是说，如果您没有特定项目的权限并且您尝试使用 GetItem，则报告的错误将是该项目在商店中不存在（这有点欺骗）。

您需要开始对您在标头中发出的所有 EWS 请求进行版本控制

  <soap:Header>
      <t:RequestServerVersion Version="Exchange2010_SP2" />
    </soap:Header>

您需要输入您正在使用的架构版本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取正确的 ID）。
