Question

尝试了我发现的所有内容，并使用EWS服务上的AutodiscoverUrl调用继续收到此错误。

尝试过提供webcredentials，networkcredentials和none。如果我自己设置service.Url属性，那么它的工作原理。我可以访问EWS电话没问题。

这是错误时的调用堆栈。

An unhandled exception of type 'Microsoft.Exchange.WebServices.Data.AutodiscoverLocalException' occurred in Microsoft.Exchange.WebServices.dll

Additional information: The Autodiscover service couldn't be located.

我还检查过我可以通过dns entry autodiscover ping Exchange服务器。我已经检查了AD的SCP，看起来还不错。 Outlook可以发现自动发现没有问题。只有我的代码不能。

如果重要，我的所有机器都是虚拟子网上的Azure vm。

我的代码：

ExchangeService service = new ExchangeService(ExchangeVersion.Exchange2013_SP1);
service.AutodiscoverUrl("Lyynx@ocean.lythixdesigns.com"); // Exception is thrown here

在反编译和调试抛出的异常后，我发现由于使用自签名证书，它不允许使用自动发现URL。

此网址显示如何将证书复制到Internet Explorer中的“受信任的根证书颁发机构”文件夹中。我以管理员身份运行IE并将其复制进来。我的代码现在可以运行了。它还有一个例外，它说它没有经过身份验证，但我认为这就是它使用登录凭据的地方。

所以相信证书就是我的问题的答案。

自动发现服务无法在C＃中找到，但适用于Outlook
