Answer 1

I changed a little of code and it tested successfully (from Hotmail to Gmail)

SmtpClient SmtpServer = new SmtpClient("smtp.live.com");
var mail = new MailMessage();
mail.From = new MailAddress("youremail@hotmail.com");
mail.To.Add("to@gmail.com");
mail.Subject = "Test Mail - 1";
mail.IsBodyHtml = true;
string htmlBody;
htmlBody = "Write some HTML code here";
mail.Body = htmlBody;
SmtpServer.Port = 587;
SmtpServer.UseDefaultCredentials = false;
SmtpServer.Credentials = new System.Net.NetworkCredential("youremail@hotmail.com", "password");
SmtpServer.EnableSsl = true;
SmtpServer.Send(mail);
