我无法连接到IMAP商店。它现在工作得更早，现在抛出错误
javax.mail.AuthenticationFailedException: AUTHENTICATE failed.
at com.sun.mail.imap.IMAPStore.protocolConnect(IMAPStore.java:474)
at javax.mail.Service.connect(Service.java:275)
at javax.mail.Service.connect(Service.java:156)
at javax.mail.Service.connect(Service.java:176)
代码：
Properties properties = new Properties();
properties.put("mail.imap.host", "outlook.office365.com"));
properties.put("mail.imap.port", "993");
properties.setProperty("mail.imap.socketFactory.class", "javax.net.ssl.SSLSocketFactory");
properties.setProperty("mail.imap.socketFactory.fallback", "false");
properties.setProperty("mail.imap.socketFactory.port", String.valueOf("993")));
session = Session.getInstance(properties);
store = session.get("imap");
store.connect(username,password);
我检查了所有的链接，我尝试了一些建议的解决方案，但他们的工作。
调试信息。

答案 1 :(得分：1)
创建应用程序密码并使用它，而不是提供普通密码。
登录到Office 365的步骤获得了MYAccount->安全和隐私->其他安全验证->创建和管理应用密码
仅使用以下属性
Properties props = new Properties();
props.put("mail.imap.host", "outlook.office365.com");
props.setProperty("mail.imap.starttls.enable", "true");
props.setProperty("mail.imaps.port", "993");
props.setProperty("mail.debug", "true");

从最近升级的Outlook Office365帐户读取电子邮件时，我也遇到了这个问题。
我将代码更改为使用microsoft ews-java-api，并已解决问题。
使用microsoft ews-java-api建立连接并阅读带有附件和已通过主题的电子邮件的示例代码：

ExchangeCredentials credentials = new WebCredentials(email, password);
service.setUrl(new URI("https://outlook.office365.com/EWS/Exchange.asmx"));

return service;
}
private static void readAttachmentEmail(ExchangeService service) throws Exception {
// Bind to the Inbox.

FileAttachment attachment = (FileAttachment) message.getAttachments().getItems().get(0);
attachment.load(" < attachment save directory > "+attachment.getName());
}
}
