摘要：
我在使用 webdav连接到运行 FBA 的 exchange 2007 mailbox 时遇到问题，该 使用 webdav 使用我的 C# 代码运行。
详：
下面的代码必须针对 Exchange 2007 服务器、连接邮箱并从邮箱读取电子邮件。
我尝试过 EWS，但它没有意义，我无法让它工作。
下面是我的代码。我正在使用 Outlook 网址来获取我需要通过 webdav 登录到交换网址的 cookie。
错误：
440 login timeout on the request.
我的代码中断的区域：
Response = (HttpWebResponse)Request.GetResponse();
法典：

每当启用 FBA 并且对 Exchange 2003/2007 发出 HTTP 请求或 WebDav 请求时，服务器都会发出HTTP/1.1 440登录超时。以下是一些示例代码，以下是有关亚马逊物流的详细信息
