MVC Azure SendGrid

У меня есть метод действия контроллера при запуске данных публикации в метод ForgotPassword:

[ValidateAntiForgeryToken]
    public async Task<ActionResult> ForgotPassword(ForgotPasswordViewModel model)
    {
        if (ModelState.IsValid)
        {
            var user = await UserManager.FindByNameAsync(model.Email);
            if (user == null || !(await UserManager.IsEmailConfirmedAsync(user.Id)))
            {
                // Don't reveal that the user does not exist or is not confirmed
                return View("ForgotPasswordConfirmation");
            }

            string code = await UserManager.GeneratePasswordResetTokenAsync(user.Id);
            var callbackUrl = Url.Action("ResetPassword", "Account", new { userId = user.Id, code = code }, protocol: Request.Url.Scheme);
            await UserManager.SendEmailAsync(user.Id, "Reset Password", "Please reset your password by clicking <a href=\"" + callbackUrl + "\">here</a>");
            return RedirectToAction("ForgotPasswordConfirmation", "Account");
        }

        // If we got this far, something failed, redisplay form
        return View(model);

    }

файл web.config

    <appSettings>
      <add key = "webpages:Version" value = "3.0.0.0" />
      <add key = "SendGridUsername" value = "XXXXXXXXXXXXXXXXXXXXXX" />
      <add key = "SendGridPassword" value = "XXXXXXXXXXXXXX" />
      <add key = "SendGridApiKey" value = "XXXXXXXXXXXXXXXXXXXXXXXXXXXX" />
    </appSettings>

Мой файл IdentityConfig выглядит так:

 public class EmailService : IIdentityMessageService
{
    public async Task SendAsync(IdentityMessage message)
    {
        await configSendGridasync(message);
    }

    // Use NuGet to install SendGrid (Basic C# client lib) 
    private async Task configSendGridasync(IdentityMessage message)
    {
        var myMessage = new SendGridMessage();
        myMessage.AddTo(message.Destination);
        myMessage.From = new System.Net.Mail.MailAddress(
                            "[email protected]", "Joe S.");
        myMessage.Subject = message.Subject;
        myMessage.Text = message.Body;
        myMessage.Html = message.Body;

        var credentials = new NetworkCredential(
                   ConfigurationManager.AppSettings["SendGridUsername"],
                   ConfigurationManager.AppSettings["SendGridPassword"]
                   );

        // Create a Web transport for sending email.
        var transportWeb = new Web(credentials);

        // Send the email.
        if (transportWeb != null)
        {
            await transportWeb.DeliverAsync(myMessage);
        }
        else
        {
            Trace.TraceError("Failed to create Web transport.");
            await Task.FromResult(0);
        }
    }

}

Однако электронное письмо не отправляется, что я делаю не так и как я могу это исправить, поскольку я выполнил инструкции из сообщения Рика Андерсона на msdn.
