我有一段Java代码(如下所示),已经有一段时间没有更改过,并且两周前曾经工作过。现在当我运行它时,突然出现了“AUTHENTICATE FAILED”的错误。我在两台不同的PC上都遇到了这个错误,并验证了使用的凭据在我使用浏览器登录我的Office365邮箱时仍然有效。
Office365这边有什么变化我应该知道吗?
我得到的错误信息是:
javax.mail.AuthenticationFailedException: AUTHENTICATE failed.
at com.sun.mail.imap.IMAPStore.protocolConnect(IMAPStore.java:732)
at javax.mail.Service.connect(Service.java:366)
at javax.mail.Service.connect(Service.java:246)
at my.application.input.imap.ImapMailBoxReader.processOnMessages(ImapMailBoxReader.java:69)
深入挖掘后,原因似乎是一个 A3 NO AUTHENTICATE failed. 的响应(javax.mail.IMAPStore的第730行)。
我使用的代码如下(使用的是javax.mail版本1.6.2):

这段代码两周前还可以正常运行,但我并没有进行任何修改且凭证仍然有效...
欢迎提出所有建议。
