SMTP setup with Microsoft tenant using modern authentication

We’d like to use n8n to send emails to mailboxes in our own Microsoft tenant.

We must have MFA enforced across all user accounts in our tenant, and we have modern authentication required, meaning “legacy” authentication protocols, like authenticated SMTP, are disabled.

App Passwords don’t work when modern authentication is enforced.

So I was hoping we could add n8n to our SPF record and send emails via unauthenticated SMTP, but I’m struggling to find anything documented by n8n for this.

Is this possible?

Is there another way we should be trying to achieve this?
