delphi - 如何在 EWS SOAP 响应中获取更详细的错误信息？

Question

我将 SOAP 调用发布到 Exchange 网络服务（使用 Delphi 和 IpWorks TipwHTTP 组件），其中一些返回内部服务器错误（一些 CreateItem 和 UpdateItem SOAP 操作），但没有更多信息：

<?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:ErrorInternalServerError</faultcode>
<faultstring xml:lang="en-US">An internal server error occurred. The operation failed.</faultstring>
<detail>
<e:ResponseCode xmlns:e="http://schemas.microsoft.com/exchange/services/2006/errors">ErrorInternalServerError</e:ResponseCode>
<e:Message xmlns:e="http://schemas.microsoft.com/exchange/services/2006/errors">An internal server error occurred. The operation failed.</e:Message>
</detail>
</s:Fault>
</s:Body>
</s:Envelope>

使用 EWS 托管 API 时，有诸如 tracking 之类的东西，但我没有使用该 API。
下面是一个用户使用它获得更详细错误信息的示例：

<m:ResponseMessages>
  <m:FindItemResponseMessage ResponseClass="Error">
    <m:MessageText>An internal server error occurred. The operation failed.</m:MessageText>
    <m:ResponseCode>ErrorInternalServerError</m:ResponseCode>
    <m:DescriptiveLinkKey>0</m:DescriptiveLinkKey>
    <m:MessageXml>
      <t:Value Name="InnerErrorMessageText">Too many concurrent connections opened.</t:Value>
      <t:Value Name="InnerErrorResponseCode">ErrorTooManyObjectsOpened</t:Value>
      <t:Value Name="InnerErrorDescriptiveLinkKey">0</t:Value>
    </m:MessageXml>
  </m:FindItemResponseMessage>
</m:ResponseMessages>

有什么我可以添加到 SOAP 请求或 HTTP 标头中的东西，可以给我额外的错误信息吗？

（我格式化了最后一个 XML 部分）。如您所见，没有比“内部错误”更多的错误信息。

根据评论中的讨论添加：

• 我在测试应用程序中重写了一个 SOAP 请求，以使用“Exchange2010”、“Exchange2013”​​或“Exchange2016”的 RequestServerVersion，但这在 XML 响应中没有提供其他信息。
• Exchange 日志中没有任何内容。在 Exchange 中设置更详细的日志记录并没有改变这一点。
