namespace EmailExample
{
    class 
    {
        static void Main(string[] args)
        {
            SmtpClient client = new SmtpClient();
            client.Host = "smtp.office365.com";
            client.Port = 587;
            client.EnableSsl = true;
            client.Credentials = new System.Net.NetworkCredential("your-email@example.com", "your-password");

            MailMessage message = new MailMessage();
            message.From = new MailAddress("your-email@example.com");
            message.To.Add("recipient@example.com");
            message.Subject = " from ASP.NET";
            message.Body = "This is a test email sent from an ASP.NET application using Office 365 Online Exchange.";
