Hi all ,
When I try sending out a test email from the email profile which uses office365 smtp
I get javax.mail.AuthenticationFailedException: 535 5.7.3 Authentication unsuccessful
I have a token setup
and on Azure I these are the API Permissions:
This is the scope I am using:
This is the SMTP server settings:
What am I doing wrong , is there a setting that I have missed?
I am experiencing this same error after an update to 8.1.45 from 8.1.28.
Were you able to find the solution?
Digging into this further it is likely a config on the Exchange Online configuration.
Authentication unsuccessful (from - Microsoft Community
Still troubleshooting currently. Re-enabling the TLSv1 and TLSv1.1 in the java.security did not resolve the problem.
Quick update on this- I was actually using Classic not OAuth like OP.
The root of my issue was entirely in the Office 365 setup. The user had the license removed on their account.

Can please you describe your setup process in Office365.
I want to see if I'm missing something.
