Send email using Outlook.com SMTP

I am trying to send an automated email using Outlook.com smtp support. However I am get the following exception:

System.Net.Mail.SmtpException: Failure sendi         


        

Answer 1

I know that this is an extremely old question and I might not even be able to help, however I had a similar problem when I tried to send an email using C#.

As a result I used this which allowed me to send the emails:

string _sender = "";
        string _password = "";

        SmtpClient client = new SmtpClient("smtp-mail.outlook.com");

        client.Port = 587;
        client.DeliveryMethod = SmtpDeliveryMethod.Network;
        client.UseDefaultCredentials = false;
        System.Net.NetworkCredential credentials =
            new System.Net.NetworkCredential(_sender, _password);
        client.EnableSsl = true;
        client.Credentials = credentials;

        MailMessage message = new MailMessage(_sender, "recipient of email");
        message.Subject = "";
        message.Body = "";
        client.Send(message);

This probably will be of no use to you anymore, but in case anyone stumbles onto this question at least there is an answer which has working code acting as a fix!
