smtp.live.com

smtp.live.com - 邮箱不可用。(smtp.live.com - mailbox unavailable. The server response was: 5.7.3 requested action aborted; user not authenticated)

我已经阅读了stackoverflow上的其他答案。 但没有一个解决方案适用于我。

我试图通过live.com发送电子邮件，但无法发送。

错误消息：

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

代码：

MailMessage mail = new MailMessage(); mail.From = new MailAddress("email@live.com"); mail.To.Add("someone@someone.com"); 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("email@live.com", "password"); smtp.Send(mail);

您是否可以使用上述代码发送电子邮件？

它在去年之前有效，但现在不再有效。

什么改变了？

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("email@live.com"); mail.To.Add("someone@someone.com"); 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("email@live.com", "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?

最满意答案

我遇到了一个问题，我无法使用特定主机上的smtp.live.com SMTP服务器发送电子邮件 - 特别是Azure主机。 在我的情况中，SMTP尝试来自我以前从未使用过的主机，因此尝试被5.7.3错误阻止：

信箱不可用。 服务器响应是：5.7.3请求的操作中止; 用户未通过身份验证

解决方案是浏览到帐户设置，在最近的活动中找到SMTP请求，然后选择“这就是我”：

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":
