我相信你有错误的服务器地址。看看这里： http://windows.microsoft.com/en-us/windows/outlook/send-receive-from-app

使用正确的地址供您使用。

string mailServer = "smtp-mail.outlook.com";

SmtpClient client = new SmtpClient(mailServer, 25); // or 587
client.DeliveryMethod = SmtpDeliveryMethod.Network;
client.EnableSsl = true;
client.UseDefaultCredentials = false;

var AuthenticationDetails = new NetworkCredential("user@domain.com", "password");
client.Credentials = AuthenticationDetails;

using (MailMessage message = new MailMessage("user@domain.com", recipient))
{
    message.IsBodyHtml = true;
    message.Body = htmlString;
    message.Subject = "Test Email";

    client.Send(message);
}
