此代码适用于本地，Exchange托管了VM，但在尝试从客户端Exchange服务器接收邮件时却无法使用。
重点是检查邮箱，提取详细信息，启动工作流并在电子邮件中附加电子邮件和任何其他附件，并将电子邮件从“收件箱”文件夹移动到我的自定义文件夹“已保存”。这一切都适用于我的本地机器。
这些是我得到的错误：
请求失败。基础连接已关闭：发送时发生意外错误。
内部异常：无法从传输连接读取数据：远程主机强行关闭现有连接。
我的代码在这一点上断了：
FindItemsResults<Item> findResults = service.FindItems(WellKnownFolderName.Inbox, view);
请原谅任何其他糟糕的代码，它不是生产准备好的，这是我编辑的缩短版本，因此可能缺少项目。
这是代码的其余部分。 （我有一个单独的类来执行身份验证并保存邮箱的所有凭据。我已经列出了第一个）

答案 0 :(得分：0)
我发现了这个问题，因为我必须从客户端的服务器工程师处获取额外信息。在尝试了一堆操作系统后，我们发现了这个问题。问题出在这里：
Uri myUri = new Uri("https://IPAddress/ews/exchange.asmx");
我在使用Exchange服务器的IP地址。相反，我必须通过webmail和公司domian
Uri myUri = new Uri("https://webmail.CompanyDomain.com/ews/exchange.asmx");
然后这项服务有效。希望这可以帮助那些遇到这样问题的人。
