JavaMail - 阅读 Outlook 邮件时出现 AuthenticationFailedException

Question

I'm using below code to read outlook email using Java mail 1.6.2

          Properties props = new Properties();        
          props.setProperty("mail.imap.ssl.enable", "true");     
          Session mailSession = Session.getInstance(props); 
          mailSession.setDebug(true);
          Store mailStore = mailSession.getStore("imap");
          mailStore.connect("outlook.office365.com", "abc@company.com", "password");

However i'm getting below error even though login credentials are proper. Please find the logs below :

Any idea what could be the reason?

Problem was wrong host ! replaced outlook.office365.com (imap-mail.outlook.com) to company specific host and it worked !

mailStore.connect("mail.ad.company.com", "abc@company.com", "password");
