使用Java从Microsoft mail Exchange server读取带有附件的邮件

我一直在尝试使用java代码从我的Microsoft exchange服务器检索电子邮件

这是我的密码

我已经做了几乎所有的事情，我得到了一个身份验证异常

javax.mail.AuthenticationFailedException:[AUTH]身份验证 失败了

但我可以通过

live.com

网站登录

有人建议您退出吗？

有：您在获取邮件会话时错过了验证器：

Authenticator authenticator=new Authenticator()
{
    @Override
    protected PasswordAuthentication getPasswordAuthentication()
    {
        return new PasswordAuthentication(userName, password);
    }
};
properties.setProperty("mail.pop3.auth", "true");
Session session=Session.getInstance(props, authenticator);

顺便说一句，您有两个会话初始化：删除其中一个。

是：您在获取邮件会话时错过了身份验证程序：
