我有EWS肥皂请求：

<?xml version="1.0" encoding="utf-8"?>

            </m:ItemIds>
        </m:GetItem>

响应错误是：

为什么会失败？

完美运作

编辑1：

我删除了遍历属性而不是出错：

<?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:LineNumber>3</t:LineNumber>
                    <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>

最后得到了这个错误。

    xmlns:s="http://schemas.xmlsoap.org/soap/envelope/">
    <s:Header>

GetItem元素中没有遍历属性，您可以查看参考文档https://msdn.microsoft.com/en-us/library/aa563775(v=exchg.150).aspx

遍历仅在FindItem和FindFolder操作中有效（它指定您要搜索的文件夹的范围）。 GetItem只是获取您拥有Id的特定项目（该Id包含用于查找项目的信息，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Item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（这有点欺骗）。

您需要开始对您在例如标题

中所做的所有EWS请求进行版本控制 

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

您需要使用您正在使用的架构版本https://msdn.microsoft.com/en-us/library/office/dn741586(v=exchg.150).aspx（或者至少放置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）。
