public bool SendEMail(){
   MailMessage mailNew = new MailMessage();
    var smtp = new SmtpClient("SmtpServer")
    {
     EnableSsl = false,
     DeliveryMethod = SmtpDeliveryMethod.Network
     };
    smtp.Port = 587;
    smtp.DeliveryMethod = SmtpDeliveryMethod.Network;
    smtp.UseDefaultCredentials = false;
    System.Net.NetworkCredential credentials = new System.Net.NetworkCredential("UserName", "password");
    smtp.EnableSsl = false;
    smtp.Credentials = credentials;
    MailAddress mailFrom = new MailAddress("clark@gmail.com");
    mailNew.From = mailFrom;
    mailNew.To.Add("someone@gmail.com");
    mailNew.Subject = Subject;
    mailNew.IsBodyHtml = Html;
    mailNew.Body = Body;
   smtp.Send(mailNew);
   return true;
}

I want to add coding for storing the sent mail in sent folder of outlook in the above code.
