【问题描述】：

我有这个代码

ExchangeService serviceInstance;
            serviceInstance = new ExchangeService(ExchangeVersion.Exchange2007_SP1);
            serviceInstance.Credentials = new WebCredentials("Jacob.Alley", "*****", "emaildomain");
            serviceInstance.TraceEnabled = true;
            serviceInstance.AutodiscoverUrl("Jacob.Alley@emaildomain.com");

我收到“找不到自动发现服务”错误。这是痕迹

我知道我有正确的电子邮件地址/用户名/密码，但我不确定如何破译跟踪信息，或者我是否做错了什么。

【解决方案1】：

如果您查看跟踪，似乎没有为自动发现配置任何 DNS 记录，例如“无法解析远程名称”

Active Directory 的 SCP 查找成功，但它尝试使用的 URL 与 Web 服务器上的 SSL 证书不匹配“（底层连接已关闭：无法为 SSL/TLS 安全通道建立信任关系"。如果这只是一个开发服务器，您可以通过使用 SSL 绕过来忽略该错误

System.Net.ServicePointManager.ServerCertificateValidationCallback +=
(se, cert, chain, sslerror) =>
    {
        return true;
    };

您可以使用 https://testconnectivity.microsoft.com/ 在外部测试自动发现
