Question

我正在ASP.NET MVC上开发Exchange Web服务托管API客户端。一切正常，直到我们昨天安装了最新的Exchange CU更新。然后，当我连接到EWS时，我在Web服务器上一段时间后定期得到“目标主体名称不正确”错误。通过重新启动Web服务器可以暂时修复这些问题。

然后我使用这篇文章正确配置了Kerberos：Set up Kerberos Authentication with Delegation on IIS 7 w/ Windows Server 2008

现在我遇到了以前从未遇到过的错误：

Exception Details: System.Xml.XmlException: Root element is missing.
[XmlException: Root element is missing.]
   System.Xml.XmlTextReaderImpl.Throw(Exception e) +88
   System.Xml.XmlTextReaderImpl.ParseDocumentContent() +1383
   System.Xml.XmlCharCheckingReader.Read() +153
   Microsoft.Exchange.WebServices.Data.EwsXmlReader.Read() +63
   Microsoft.Exchange.WebServices.Data.EwsXmlReader.Read(XmlNodeType nodeType) +44
   Microsoft.Exchange.WebServices.Data.ServiceRequestBase.ReadXmlDeclaration(EwsServiceXmlReader reader) +54

[ServiceRequestException: The response received from the service didn't contain valid XML.]
   Microsoft.Exchange.WebServices.Data.ServiceRequestBase.ReadXmlDeclaration(EwsServiceXmlReader reader) +165
   Microsoft.Exchange.WebServices.Data.ServiceRequestBase.ReadSoapFault(EwsServiceXmlReader reader) +43
   Microsoft.Exchange.WebServices.Data.ServiceRequestBase.ProcessWebException(WebException webException) +413
   Microsoft.Exchange.WebServices.Data.ServiceRequestBase.GetEwsHttpWebResponse(IEwsHttpWebRequest request) +139
   Microsoft.Exchange.WebServices.Data.ServiceRequestBase.ValidateAndEmitRequest(IEwsHttpWebRequest& request) +573
   Microsoft.Exchange.WebServices.Data.MultiResponseServiceRequest`1.Execute() +42
   Microsoft.Exchange.WebServices.Data.ExchangeService.FindAppointments(FolderId parentFolderId, CalendarView calendarView) +104

因为这是Exchange Web Services API的托管版本，所以我直接与XML请求和响应无关。它对我来说基本上是一个黑盒子。从错误中可以看出，它是在从EWS调用数据时发生的。

EWS托管：缺少根元素
