Test this Code:

        MailMessage mail = new MailMessage();
        SmtpClient SmtpServer = new SmtpClient("smtp.live.com");

        mail.From = new MailAddress("mawlud.f.m@hotmail.com");
        mail.To.Add("mawlud.f.m@gmail.com");

        mail.Subject = "Mail Subject";
        mail.Body = "Mail Body";

        SmtpServer.Port = 587;
        SmtpServer.Credentials = new System.Net.NetworkCredential("mawlud.f.m@hotmail.com", "Write Your Password");

        SmtpServer.EnableSsl = true;
        SmtpServer.Send(mail);
