Question

我想查询我的电子邮件文件夹，查找我写在其上的自定义标题的特定电子邮件。但似乎我正在创建的SOAP消息有一些问题，它总是返回空结果集。

我确定我在该文件夹中有电子邮件。如果我在删除限制部分后查询，我可以在查询结果中看到该电子邮件。如果我连接到我的帐户，让我们说Thunderbird，那么我可以看到标题就在那里。

到目前为止，我至少搜索了一周，我唯一能找到的结果是https://social.msdn.microsoft.com/Forums/exchange/en-US/8db4b750-d92f-489b-8282-d109d33314ff/using-finditem-request-to-find-the-items-with-given-header-value，最后只是告诉我我的实施应该有效。

感谢阅读。

如果我还尝试使用AllProperties基本形状查询服务器并将我的标题添加到extendedfielduri，那么我会得到我的标题作为回应。

在此之后我还试着看看在我的查询中添加相同的参数是否有效。但没有运气。以下查询返回的响应与第一个完全相同。

Answer 1

所有Internet标头都应该是纯字符串，所以在您的代码中

<t:ExtendedFieldURI DistinguishedPropertySetId="InternetHeaders" PropertyName="X-My-Header" PropertyType="StringArray"/>

需要

另外我建议你先试着看看EWS是否会将Header作为附加属性返回，例如

<?xml version="1.0"?>
<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:t="http://schemas.microsoft.com/exchange/services/2006/types" xmlns:m="http://schemas.microsoft.com/exchange/services/2006/messages">
  <soap:Header>
    <t:RequestServerVersion Version="Exchange2010"/>
  </soap:Header>
  <soap:Body>
    <FindItem xmlns="http://schemas.microsoft.com/exchange/services/2006/messages" Traversal="Shallow">
      <ItemShape>
<t:BaseShape>Default</t:BaseShape>
  <t:AdditionalProperties>
           <t:ExtendedFieldURI DistinguishedPropertySetId="InternetHeaders" PropertyName="X-My-Header" PropertyType="String"/>
          </t:AdditionalProperties>
      </ItemShape>
      <m:ParentFolderIds>
<t:FolderId Id="AQMkADAwATM0MDAAMS1jMzg1LWZkMDMtMDACLTAwCgAuAAADlxvq+JrhgkiMcRwVFQDzo9MBANxoXUHEHORLhWKXuo92RaUAAAIBDwAAAA=="/>

如果您没有看到您的财产与物品一起返回，那么限制将无效。通常使用X-Headers，他们需要配置https://msdn.microsoft.com/en-us/library/office/dn596091(v=exchg.150).aspx，然后当你使用像MFCMapi或OutlookSpy这样的Mapi编辑器查看Item时，你应该将它们看作一个单独的Extended属性。

使用X标头MS Exchange查询文件夹
