通过Exchange Online的（365处）发送使用System.Net.Mail SMTP电子邮件 [英] Send SMTP email using System.Net.Mail via Exchange Online (Office 365)

问题描述

我们正在测试新的Office 365测试版，我对Exchange Online服务邮件帐户。现在，我尝试连接一个LOB应用程序，可以从我的测试帐户发送SMTP电子邮件。

不过交易所365平台需要在端口587 TLS加密，并有 System.Net.Mail 的'功能'是不允许隐式SSL加密。

有没有人设法让C＃通过这个平台发送邮件？

我有以下的基本代码，应。发送邮件 - 任何意见，将不胜感激。

  SmtpClient服务器=新SmtpClient（ServerAddress）; 
 server.Port = 587; 
 server.EnableSsl = TRUE; 
 server.Credentials =新System.Net.NetworkCredential（[e-mail]，密码）; 
 server.Timeout = 5000; 
 server.UseDefaultCredentials = FALSE; 
 
邮件MAILMESSAGE新= MAILMESSAGE（）; 
 mail.From =新的MailAddress（recipent @ anyaddress）; 
 mail.To.Add（[e-mail]）; 
 mail.Subject =测试出消息发送; 
 mail.Body =这是我的邮件正文; 
 mail.IsBodyHtml = TRUE; 
 
 server.Send（邮件）; 
  

解决方案

固定在上面的工作代码的几个错别字：

 味精MAILMESSAGE新= MAILMESSAGE（）; 
 msg.To.Add（新MailAddress（[e-mail]，某人））; 
 msg.From =新的MailAddress（[e-mail]，你）; 
 msg.Subject =这是一个测试邮件; 
 msg.Body =这是使用Exchange Online的测试消息; 
 msg.IsBodyHtml = TRUE; 
 
 SmtpClient客户端=新SmtpClient（）; 
 client.UseDefaultCredentials = FALSE; 
 client.Credentials =新System.Net.NetworkCredential（用户名，密码）; 
 client.Port = 587; //您可以使用端口25，如果587被封锁（我的是！）
 client.Host =smtp.office365.com; 
 client.DeliveryMethod = SmtpDeliveryMethod.Network; 
 client.EnableSsl = TRUE; 
试
 {
 client.Send（MSG）; 
 lblText.Text =消息发送成功与 
} 
赶上（异常前）
 {
 lblText.Text = ex.ToString（）; 
} 
  

我在使用上面的代码两个Web应用程序，并没有任何麻烦都做工精细

We are testing the new Office 365 beta, and i have a mail account on the Exchange Online service. Now I'm trying to connect a LOB application that can send smtp emails from my test account.

However the Exchange 365 platform requires TLS encryption on port 587, and there is a 'feature' of System.Net.Mail that does not permit Implicit SSL encryption.

Has anyone managed to get C# sending mails via this platform?

I have the following basic code that should send the mail - any advice would be appreciated.

SmtpClient server = new SmtpClient("ServerAddress");
server.Port = 587;
server.EnableSsl = true;
server.Credentials = new System.Net.NetworkCredential("[e-mail]", "password");
server.Timeout = 5000;
server.UseDefaultCredentials = false;

MailMessage mail = new MailMessage();
mail.From = new MailAddress("recipent@anyaddress");
mail.To.Add("[e-mail]");
mail.Subject = "test out message sending";
mail.Body = "this is my message body";
mail.IsBodyHtml = true;

server.Send(mail);

解决方案

Fixed a few typos in the working code above:

    MailMessage msg = new MailMessage();
    msg.To.Add(new MailAddress("[e-mail]", "SomeOne"));
    msg.From = new MailAddress("[e-mail]", "You");
    msg.Subject = "This is a Test Mail";
    msg.Body = "This is a test message using Exchange OnLine";
    msg.IsBodyHtml = true;

    SmtpClient client = new SmtpClient();
    client.UseDefaultCredentials = false;
    client.Credentials = new System.Net.NetworkCredential("your user name", "your password");
    client.Port = 587; // You can use Port 25 if 587 is blocked (mine is!)
    client.Host = "smtp.office365.com";
    client.DeliveryMethod = SmtpDeliveryMethod.Network;
    client.EnableSsl = true;
    try
    {
        client.Send(msg);
        lblText.Text = "Message Sent Succesfully";
    }
    catch (Exception ex)
    {
        lblText.Text = ex.ToString();
    }

I have two web applications using the above code and both work fine without any trouble.
