报错： Unauthorized
代码如下：
ExchangeService service = new ExchangeService(ExchangeVersion.Exchange2013_SP1);
service.UseDefaultCredentials = false;
service.Credentials = new WebCredentials("mym@jntxd.com", "password");
service.Url = new Uri("https://jntxd.com/ews/exchange.asmx");
EmailMessage message1 = new EmailMessage(service);
message1.ToRecipients.Add("yuanxu@jntxd.com");
message1.Subject = "Status Update";
message1.Body = "Project complete!";
message1.Send();
Exchange： 2013 SP1
DNS：jntxd.com正常解析，nslookup检查地址是对的，可ping通，且已进行CA签名
域：ActiveDirectory已部署，测试机已加入域，通过Web App可发送邮件
SSL设置：
身份验证：

已验证同样的代码可以向outlook.com发送邮件，所以个人觉得问题应该是出在服务器配置上面
请大家多帮忙
