    Using GoDaddy Provided Office365 Email for ASP.NET Contact Form


    I am trying to add a web form that takes an input and sends an email from a godaddy-provided office365 email account to my personal email. I am building this in asp.net using Visual Studio 2017. I have been able to get it to publish onto my website and be live, but it gives me the following exception when I fill out the form and try to submit it:

    System.Net.Mail.SmtpException: Failure sending mail. ---> System.Net.WebException: Unable to connect to the remote server ---> System.Net.Sockets.SocketException: An attempt was made to access a socket in a way forbidden by its access permissions at System.Net.Sockets.Socket.DoConnect(EndPoint endPointSnapshot, SocketAddress socketAddress) at System.Net.ServicePoint.ConnectSocketInternal(Boolean connectFailure, Socket s4, Socket s6, Socket& socket, IPAddress& address, ConnectSocketState state, IAsyncResult asyncResult, Exception& exception) --- End of inner exception stack trace --- at System.Net.ServicePoint.GetConnection(PooledStream PooledStream, Object owner, Boolean async, IPAddress& address, Socket& abortSocket, Socket& abortSocket6) at System.Net.PooledStream.Activate(Object owningObject, Boolean async, GeneralAsyncDelegate asyncCallback) at System.Net.PooledStream.Activate(Object owningObject, GeneralAsyncDelegate asyncCallback) at System.Net.ConnectionPool.GetConnection(Object owningObject, GeneralAsyncDelegate asyncCallback, Int32 creationTimeout) at System.Net.Mail.SmtpConnection.GetConnection(ServicePoint servicePoint) at System.Net.Mail.SmtpTransport.GetConnection(ServicePoint servicePoint) at System.Net.Mail.SmtpClient.GetConnection() at System.Net.Mail.SmtpClient.Send(MailMessage message) --- End of inner exception stack trace --- at System.Net.Mail.SmtpClient.Send(MailMessage message) at ShootingStarsEvent.contact.btnSend_Click(Object sender, EventArgs e) in D:\OneDrive\Projects\ShootingStarsEvent\ShootingStarsEvent\ShootingStarsEvent\contact.aspx.cs:line 132

    I have the following section in my web.config file:

          <smtp from="human@shootingstarsevent.com">
            <network host="relay-hosting.secureserver.net" port="25" />

    and here is the code that is supposed to send the email. It works when I run this code locally, but it fails when it is actually present on the godaddy server.

                MailMessage msg = new MailMessage();
                msg.To.Add("MY PERSONAL EMAIL");
                MailAddress address = new MailAddress("human@shootingstarsevent.com");
                msg.From = address;
                msg.Subject = "Contact Requested From " + tBoxName.Text;
                msg.Body = "Reply Back To " + tBoxEmail.Text + "\n\n\nMessage: " + tBoxMessage.Text;
                SmtpClient client = new SmtpClient();
                client.Host = "smtp.office365.com";
                client.Port = 25;
                client.EnableSsl = true;
                client.UseDefaultCredentials = false;
    NetworkCredential credentials = new NetworkCredential("human@shootingstarsevent.com", "MY PASSWORD", "shootingstarsevent.com");
                client.Credentials = credentials;
                //Send the msg
                    lblResult.Text = "Message Successfully Sent!";
                    tBoxName.Text = "";
                    tBoxMessage.Text = "";
                    tBoxEmail.Text = "";
                catch (Exception ex)
                    lblResult.Text = ex.ToString();
                    tBoxName.Text = "";
                    tBoxMessage.Text = "";
                    tBoxEmail.Text = "";


    Do any of you have any ideas what I could do to get this working?

    Did you ever get your smtpclient code to work


    Re: Using GoDaddy Provided Office365 Email for ASP.NET Contact Form

    Got this working with the following settings:

    SmtpClient client = new SmtpClient {

       Host = "smtp.office365.com",

       Credentials = new NetworkCredential("<FULL USERNAME@DOMAIN.COM", ConfigurationManager.AppSettings["password"]),

       Port = 587,

       EnableSsl = true,

       Timeout = 10000
