Sending email using Smtp.mail.microsoftonline.com

Question

The context:

We’re a small company that does not have an Exchange Server (or anyone dedicated to it) yet we still need to have/send emails.

Answer 1

you can try this sample

      private void Button1_Click(System.Object sender, System.EventArgs e)
    {
        try
        {
            MailMessage myMessage = new MailMessage();
            SmtpClient myClient = new SmtpClient("yourserver");
            myClient.Port = "587";
            myClient.Host = "your server";
            myClient.UseDefaultCredentials = false;
            myClient.Credentials = new System.Net.NetworkCredential("username", "password");


            myMessage.From = new MailAddress("sender");
            myMessage.To.Add("recipient");
            myMessage.Subject = "Subject email";
            myMessage.Body = "body email";
            myClient.EnableSsl = true;
            myClient.Send(myMessage);
        }

        catch (Exepiton ex)
        {
            MessageBox.Show(ex.Message.ToString());
        }
    }
