    I try to use Microsoft365 but it’s not working. What I have done already:

    • I made the whole setup exactly how it’s explained on your website: https://fluentsmtp.com/docs/setup-outlook-with-fluentsmtp/
    • yes I copied the right credentials, otherwise I wouldn’t even receive a token. (How I know that? Because I tried all of the credentials. I tried with the user token, I tried the app token…)
    • I activated on MS365 Admin the SMTP Auth, which is disabled normally
    • I gave me the role on the app
    • I checked the API permissions on the App, so all Mail-Permissions like “mail.send” are in the app, even with admin consent
    • and last but not least, yes I am using the admin account / same account which is displayed on fluent-smtp

    I receive the token and everything looks fine but when I try to send a test-mail, it gives me the error “422 unauthorized”. Is there any step I am missing? Is there something I need to enable on ms365 admin center or azure?
