Getting Error (Login denied(ec=67)

Hello guys so im new to urbackup and im trying set-up mail notifications but i keep getting “(Login denied(ec=67)”.
Since google removed the “less secure apps” im using outlook and my current settings are:

Mail server: smtp.office365.com
Mail server port: 587
Mail server username: sendingemail @outlook.pt
Mail server password: tried the password i use to login and app passwords
Sender E-Mail Address: sendingemail @outlook.pt
send mails only with SSL/TLS: tried on and off
Check SSL/TLS certificate: tried on and off
Use SSL encrypted SMTP: off
server admin mail address: myemail @gmail.com
send test mail: myemail @gmail.com

Any idea what could be causing this error ?
