Jakarta Mail OAUTH support for Office365 over POP protocol

We are trying to connect to Office365 over POP3 using OAUTH. We get the error "Protocol error. Connection is closed. 10" stacktrace mentioned below

javax.mail.AuthenticationFailedException: Protocol error. Connection is closed. 10
    at com.sun.mail.pop3.POP3Store.protocolConnect(POP3Store.java:193)
    at javax.mail.Service.connect(Service.java:342)

Below if the snipped of code we are usign to connect

   Properties props = new Properties();
   props.put("mail.pop3.ssl.enable", "true"); 
   props.put("mail.pop3s.auth.mechanisms","XOAUTH2");
   props.put("mail.debug", "true");
   session = Session.getInstance(props);
   final Store store = session.getStore("pop3s");
   store.connect("outlook.office365.com", 995, userId, accessToken);

We are able to connect to Office using IMAP protocol over OAUTH. we tried this with jakarta-mail-1.6.5 and jakarta-mail-1.6.6 both but are unable to resolve the error. Please suggest if we are connecting wrongly or there is any properties missing.

Worked with the workaround mentioned in https://github.com/eclipse-ee4j/mail/issues/461 on Jakarta-mail 1.6.6 development version.
