我已经对此进行了一段时间的研究，并尝试了几种不同的属性组合并不断收到此错误。我们能够毫无问题地使用其他 smtp 服务器（和不同的属性）成功发送电子邮件，但 Exchange 无法正常工作。

关于此主题的其他答案提到您需要 1.4.3 版或更新版本的 JavaMail，因为 Exchange 服务器需要 NTLM。我正在使用 JavaMail 1.4.7。其他答案说 Exchange 默认不支持 SMTP。

这是最新的代码：

// this is inside a Junit
String emailTo = "me@gmail.com";
String emailFrom = "me@mycompany.com";
String message = "testing exchange";
String host = "smtp.office365.com";
String user = "obfuscated";
String password = "obfuscated";

StringBuilder body = new StringBuilder(message);

Properties props = new Properties();
props.put("mail.smtp.host", host);
props.put("mail.from", "me@mycompany.com");
props.put("mail.smtp.starttls.enable", "true");
props.put("mail.smtp.auth", "true");
props.put("mail.smtp.port", "587");
props.put("mail.debug", "true");

Authenticator authenticator = new Authenticator();
props.setProperty("mail.smtp.submitter", authenticator.getPasswordAuthentication().getUserName());

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

Message message = new MimeMessage(session);
try {
    message.setFrom(new InternetAddress(as_email_from));
    message.setRecipient(Message.RecipientType.TO, new InternetAddress(as_email_to));
    message.setSubject("Testing exchange server");                
    message.setContent(body.toString(), "text/html");
    message.setSentDate(new Date());

    Transport transport = session.getTransport("smtp");
    transport.connect(host, 587, smtpSettings.getUser(), smtpSettings.getPswd());
    transport.sendMessage(message, message.getAllRecipients());
    transport.close();

} catch (Exception e) {
    e.printStackTrace();
}

private class Authenticator extends javax.mail.Authenticator {
   private PasswordAuthentication authentication;
   public Authenticator() {
       String username = "myuser";
       String password = "mypass";
       authentication = new PasswordAuthentication(username, password);
   }
   protected PasswordAuthentication getPasswordAuthentication() {
       return authentication;
   }
}

这是调试：

根据调试输出，我相信您实际上并没有使用 JavaMail 1.4.7。检查您的 CLASSPATH、服务器上的 lib 目录等。

检查您的 Exchange 服务器是否需要启用 TLS，如果需要，请通过设置此属性来启用 TLS

mail.smtp.starttls.enable=true

这解决了我的问题。
