I’m having trouble setting up my Outlook email connection in n8n and keep getting authentication errors. I’ve already done the basic setup steps like turning on IMAP/POP access in my Outlook settings and setting up two-factor authentication with an app password.
My current n8n SMTP configuration uses:
- My Outlook email address
- The app password I generated
- Port 587
- SSL/TLS turned off
- STARTTLS turned on
- Tried both smtp-mail.outlook.com and smtp.office365.com as hosts
But I keep getting this error message: “Couldn’t connect with these settings Invalid login: 535 5.7.139 Authentication unsuccessful, basic authentication is disabled.”
I’m wondering if there’s something else I need to enable in my Outlook account to make SMTP work properly. Has anyone else run into this problem? What am I missing here?
