您好，我目前正在开发Java应用程序，将通过Java邮件API（1.6.2）发送邮件给多个收件人，我已经按照微软文档配置了SMTP问题是代码与我的个人Hotmail电子邮件ID，但它失败的企业办公室365帐户。
错误：javax.mail。验证失败异常：535 5.7.3验证不成功[产品编号1PR0101CA0066.INDPRD01.PROD.OUTLOOK.COM]
POP和IMAP正在工作（接收邮件），我可以在Office 365 Web中使用密码登录，我也试过更改密码。
代码：

User user = Credentials.ACC;
Properties props = new Properties();
props.put("mail.smtp.host", "smtp.office365.com");//outlook.office365.com
props.put("mail.smtp.auth", "true");
props.put("mail.smtp.port", "587");//25
props.put("mail.smtp.starttls.enable", "true");
props.put("mail.transport.protocol", "smtp");
//props.put("mail.smtp.ssl.enable", true);

Session session = Session.getInstance(props, new Authenticator() {
    @Override
    protected PasswordAuthentication getPasswordAuthentication() {
        return new PasswordAuthentication(user.getUsername(), user.getPassword());
    }
});
session.setDebug(true);

try {
    MimeMessage msg = new MimeMessage(session);
    msg.setFrom(user.getUsername());

    msg.setRecipients(Message.RecipientType.TO,
            "some@mail.com");
    msg.setSubject("Testing SMTP using [" + user.getUsername() + "]");
    msg.setSentDate(new Date());
    msg.setText("Hey, this is a test from [" + user.getUsername() + "], Sending via Java Mail API");

    Transport.send(msg);
    System.out.println("Sent Ok");
} catch (MessagingException e) {
    System.out.println("Something went wrong");
    e.printStackTrace();
}
