smtp.live.com - 邮箱不可用。服务器响应为：5.7.3请求的操作中止;用户未通过身份验证 [英] smtp.live.com - mailbox unavailable. The server response was: 5.7.3 requested action aborted; user not authenticated

问题描述

我已经阅读了计算器其他答案。但没有一个解决方案，为我工作。

我试图通过live.com发送电子邮件，但不能把它。

错误消息：

 邮箱不可用。服务器响应为：5.7.3请求的操作中止; 
用户未通过身份验证
  

中的代码：

 邮件MAILMESSAGE新= MAILMESSAGE（）; 
 mail.From =新的MailAddress（[e-mail]）; 
 mail.To.Add（[e-mail]）; 
 mail.Subject =你好; 
 mail.Body =awefkljj kawefl 
 mail.IsBodyHtml = FALSE; 
 
 SmtpClient SMTP =新SmtpClient（smtp.live.com，587）; 
 smtp.EnableSsl = TRUE; 
 smtp.Credentials =新的NetworkCredential（[e-mail]，密码）; 
 smtp.Send（邮件）; 
  

您可以用上面的代码发送电子邮件？

它的工作原理之前，去年一年，但它已不再是现在的工作。

做了哪些改变？

I have read other answers on the stackoverflow. but none of the solutions work for me.

I'm trying to send email through live.com, but unable to it.

The error message:

mailbox unavailable. The server response was: 5.7.3 requested action aborted;
user not authenticated

The code:

MailMessage mail = new MailMessage();
mail.From = new MailAddress("[e-mail]");
mail.To.Add("[e-mail]");
mail.Subject = "hello";
mail.Body = "awefkljj kawefl";
mail.IsBodyHtml = false;

SmtpClient smtp = new SmtpClient("smtp.live.com", 587);
smtp.EnableSsl = true;
smtp.Credentials = new NetworkCredential("[e-mail]", "password");
smtp.Send(mail);

Are you able to send the email by using above code?

It works before, last year, but it is no more working now.

What had been changed?

解决方案

I ran into an issue where I was unable to send emails using the smtp.live.com SMTP server from certain hosts -- particulary Azure hosts. In my case, the SMTP attempt was from a host that I had never used to sign-in previously, so the attempt was blocked with the 5.7.3 error:

Mailbox unavailable. The server response was: 5.7.3 requested action aborted; user not authenticated

The solution was to browse to the account settings, locate the SMTP request in its recent activity, and select "This was me":
