Having issues setting Office 365 as relay in postfix

yum install cyrus-sasl cyrus-sasl-plain cyrus-sasl-md5

sasl_passwd:

[smtp.office365.com]:587 user@xompany.com:password

main.cf:

relayhost = [smtp.office365.com]:587
smtp_sasl_password_maps = hash:/etc/postfix/sasl_passwd
smtp_sasl_auth_enable = yes
smtp_generic_maps = hash:/etc/postfix/generic

smtp_tls_security_level = may
smtp_sasl_security_options = noanonymous

cat /etc/sasl2/smtpd.conf

pwcheck_method: saslauthd

mech_list: plain login

Error:

localhost postfix/smtp[6073]: 60B1E400E9F9: SASL authentication failed; server smtp.office365.com[40.101.77.82] said: 535 5.7.3 Authentication unsuccessful [VI1PR07CA0165.eurprd07.prod.outlook.com]

what am i missing ? I see in some guides SSL certificates are used, if it's a must, what's procedure to obtain them ?
