Bounced with office 365


I’ve some trouble to connect office365 shared mailbox with pop protocol to handle bounce

I put this in config.php :
$bounce_mailbox_host = ‘’;
$bounce_mailbox_user = ‘’;
$bounce_mailbox_password = ‘pass’;
$bounce_mailbox_port = “995/pop3/ssl/novalidate-cert”;

user has been replace for security reasons.

error : phpList - Cannot create POP3 connection to Can not authenticate to POP3 server: Authentication failure: unknown user name or bad password.
phpList - Download failed, exiting

Could you help me?
