Envoi de messages électroniques à l'aide smtp Outlook à partir asp.net mvc l'application

Question

J'ai essayé envoyer des messages électroniques à travers mon asp.net en utilisant l'application mvc le code suivant:

public ActionResult ResetPassword() 
    { 
     if (Session["id"] == null) 
     { 
      return RedirectToAction("Login", "Home"); 
     } 
     bool status = false; 

     B4URepository dalObj = new B4URepository(); 
     var customer = dalObj.GetCustomerDetails(Convert.ToInt32(Session["id"])); 
     string email = customer.EmailId; 
     string name = customer.Name; 

     MailMessage mailMessage = new MailMessage(); 
     mailMessage.To.Add(new MailAddress(email, name)); 
     mailMessage.From = new MailAddress("sender-outlook-email"); 
     //mailMessage.Sender = new MailAddress("sender-outlook-email", "sender-name"); 
     mailMessage.Subject = "<h3>Password reset</h3>"; 
     mailMessage.Body = "Hello"; 
     mailMessage.IsBodyHtml = true; 
     mailMessage.Priority = MailPriority.High; 

     SmtpClient smtp = new SmtpClient(); 

     try 
     { 
      smtp.Send(mailMessage); 
      status = true; 
     } 

     catch (Exception) 
     { 
      status = false; 
     } 
     if (status) 
      return View("Success"); 
     else 
      return View("Error"); 
    } 

et les paramètres suivants dans Web.config:

<system.net> 
<mailSettings> 
    <smtp from="sender-outlook-email"> 
    <network host="smtp-mail.outlook.com" 
      port="587" 
      userName="sender-outlook-email" 
      password="sender-password" 
      enableSsl="true"/> 
    </smtp> 
</mailSettings> 
<!--<mailSettings> 
    <smtp deliveryMethod="SpecifiedPickupDirectory"> 
    <specifiedPickupDirectory pickupDirectoryLocation="Z:\MailDump"/> 
    </smtp> 
</mailSettings>--> 

en utilisant le code commenté à savoir les paramètres de messagerie que j'ai vérifié si l'e-mail est créé et avec succès trouvé atleast il est créé et stocké dans le répertoire spécifié.

Mais essayer d'envoyer du courrier en utilisant le code ci-dessus donne une exception sur la ligne « smtp.Send (MailMessage) »:

Answer 1

Vous devez spécifier le client name et port number, puis définissez les UseDefaultCredentials false, si vous utilisez d'autres informations d'identification autre que le vôtre (les informations d'identification de loggedIn)

SmtpClient client = new SmtpClient("smtp-mail.outlook.com"); 
client.Port = 587; 
client.UseDefaultCredentials = false; 

Cela devrait fonctionner.
