Question

我在设置Outlook邮件的Outlook邮件时遇到了麻烦，我已按照here和here

的说明进行操作

Properties props = new Properties();
          props.put("mail.smtp.user", d_email);
          props.put("mail.smtp.host", "smtp-mail.outlook.com");
          props.put("mail.smtp.port", "587");
          props.put("mail.smtp.starttls.enable","true");
          props.put("mail.smtp.auth", "true");
          props.put("mail.smtp.socketFactory.port", "587");
          props.put("mail.smtp.socketFactory.class", "javax.net.ssl.SSLSocketFactory");
          props.put("mail.smtp.socketFactory.fallback", "true");

          try
          {
          Authenticator auth = new javax.mail.Authenticator() {
              protected PasswordAuthentication getPasswordAuthentication() {
                  return new PasswordAuthentication(d_email, d_password);
              }
            };

          Session session = Session.getInstance(props, auth);

          MimeMessage msg = new MimeMessage(session);
          msg.setText("Hey, this is the testing email.");
          msg.setSubject("Testing");
          msg.setFrom(new InternetAddress(d_email));
          msg.addRecipient(Message.RecipientType.TO, new InternetAddress("example@gmail.com"));
          Transport.send(msg);

          }catch (MessagingException mex) {
             mex.printStackTrace();
          }

我一直在收到错误：

javax.mail.MessagingException: Could not connect to SMTP host: smtp-mail.outlook.com, port: 587;
  nested exception is:
    javax.net.ssl.SSLException: Unrecognized SSL message, plaintext connection?
    at com.sun.mail.smtp.SMTPTransport.openServer(SMTPTransport.java:1934)
    at com.sun.mail.smtp.SMTPTransport.protocolConnect(SMTPTransport.java:638)
    at javax.mail.Service.connect(Service.java:317)
    at javax.mail.Service.connect(Service.java:176)
    at javax.mail.Service.connect(Service.java:125)

我搜索了google和stackoverflow，我想它必须使用SSL而不是TLS，因为outlook不接受TLS，否则连接将被远程主机关闭，但我从Internet找到的解决方案没有'锻炼身体。为了成功发送我的测试邮件，我错过了什么？

我是邮件API的新手，任何建议或帮助将不胜感激。感谢。

编辑：我有一个来自microsoft的电子邮件帐户我注册的类似于'xxxx@outlook.com'

删除这样的SocketFactory参数，并享受发送电子邮件。

props.put("mail.smtp.host", "smtp-mail.outlook.com");
props.put("mail.smtp.port", "587");
props.put("mail.smtp.starttls.enable","true");
props.put("mail.smtp.auth", "true");

我没有在文档中找到必要的参数。

请在没有这些道具的情况下重试：

props.put("mail.smtp.socketFactory.port", "587");
props.put("mail.smtp.socketFactory.class", "javax.net.ssl.SSLSocketFactory");
props.put("mail.smtp.socketFactory.fallback", "true");

我没有必要将它们设置为office365。 outlook.com应该是类似的

试试这个代码它对我有用

    Properties props = null;
    if (props == null) {
        props = new Properties();
        props.put("mail.smtp.auth", true);
        props.put("mail.smtp.starttls.enable", true);
        props.put("mail.smtp.host", "smtp.live.com");
        props.put("mail.smtp.port", "587");
        props.put("mail.smtp.user", User);
        props.put("mail.smtp.pwd", Pwd);
    }
    Session session = Session.getInstance(props, null);
    session.setDebug(true);
    Message msg = new MimeMessage(session);
    msg.setFrom(new InternetAddress(User));
    if (Objet != null) {
        msg.setSubject(Objet);

    }
    msg.setText(Content);
    msg.setRecipient(Message.RecipientType.TO, new InternetAddress(emailId));
    Transport transport = session.getTransport("smtp");
    transport.connect("smtp.live.com", 587, User, Pwd);
    transport.sendMessage(msg, msg.getAllRecipients());
    System.out.println("Mail sent successfully at " + emailId);
    transport.close();
}
