My company have changed from local webserver email to office 365 and now the emails are not received.
I'm trying this configuration but not working

$mailer = new PHPMailer();
 $mailer->IsSMTP();
 $mailer->SMTPDebug = 3;
 $mailer->Port = 587; 
 $mailer->Host = 'smtp.office365.com';
 $mailer->SMTPAuth = true; 
 $mailer->Username = "xxxxxx";
 $mailer->Password = "xxxxxx";
 $mailer->SMTPOptions = array(
 'ssl' => array(
 'verify_peer' => false,
 'verify_peer_name' => false,
 'allow_self_signed' => true
 )
 );
 $mailer->FromName = 'Bart S. Locaweb'; 
 $mailer->From = 'remetente@email.com.br'; 
 $mailer->AddAddress('destinatario@email.com','Nome do destinatário');
 $mailer->Subject = 'Teste enviado através do PHP Mailer SMTPLW';
 $mailer->Body = 'Este é um teste realizado com o PHP Mailer SMTPLW';
 if(!$mailer->Send())
 
 echo "Message was not sent";
 echo "Mailer Error: " . $mailer->ErrorInfo; exit; 
 print "E-mail enviado!";
 }

I have read several stuff related to this subject and the first thing to do was to check if i have connection with office 365 server...and i have

Testing smtp.gmail.com:587: successfull connected
Testing smtp.gmail.com:465: ERROR: 101 - Network is unreachable
Testing smtp.office365.com:587: successfull connected

So i don't get why i receive this notifocation

SMTP ERROR: Password command failed: 535 Incorrect authentication data
SMTP Error: Could not authenticate.
CLIENT -> SERVER: QUIT
SERVER -> CLIENT: 221 loge.dnsloge.com closing connection
Connection: closed
SMTP connect() failed. https://github.com/PHPMailer/PHPMailer/wiki/Troubleshooting
Message was not sentMailer Error: SMTP connect() failed. https://github.com/PHPMailer/PHPMailer/wiki/Troubleshooting

and the user and pass are correct....any help?
