为什么我无法使用 JavaMail（IMAP 协议）连接到我的邮箱并收到 NO AUTHENTICATE failed 错误？

Question

我正在尝试通过 JavaMail IMAP 协议连接到邮箱，但无法成功连接。

远程登录成功
能够使用相同的凭据配置 outlook web 客户端
尝试使用最新的 JavaMail 1.6.2 版本（JDK7 版本）
也尝试按照属性进行设置：mail.imap.auth.plain.disable=true

Properties props = System.getProperties();
props .setProperty("mail.store.protocol", "imap");
props .setProperty("mail.debug.auth", "true");
props .setProperty("mail.imap.ssl.enable", "true");
props .setProperty("mail.imap.auth.plain.disable", "true");
Session session = Session.getInstance(props, new javax.mail.Authenticator() {
                @Override
                protected PasswordAuthentication getPasswordAuthentication() {
                    return new PasswordAuthentication(UserName, Password);
                }
            });
session.setDebug(true);
store = session.getStore("imap");
store.connect(ServerName, Port, UserName, Password);

Answer 1

您几乎可以肯定运行遇到了 Exchange 服务器错误，它宣传它支持 PLAIN 身份验证，但实际上不支持。

调试输出没有显示您已禁用 PLAIN 身份验证，也许您的设置有误属性？您能否包括您实际使用的代码，它显示了您如何设置属性?

另请注意，您 don't need the Authenticator。

Answer 2

IMAP 协议更改为 IMAPI4，由于交换服务器停止通信并导致此问题。我们已恢复这些更改。现在，问题解决了。
