I am experiencing issues configuring my Outlook SMTP settings in n8n despite following all necessary steps. Here’s what I have done so far:
Enabled IMAP and POP in my Outlook account. Activated Two-Step Verification and created an App Password for authentication. Configured an SMTP credential in n8n, using: Email: my Outlook address App Password Port: 587 SSL/TLS: Disabled STARTTLS: Enabled Host: Tried both smtp-mail.outlook and smtp.office365 Despite this, I continuously receive the following error:
Couldn’t connect with these settings Invalid login: 535 5.7.139 Authentication unsuccessful, basic authentication is disabled. [FR4P281CA0070.DEUP281.PROD.OUTLOOK.COM 2025-02-17T11:47:55.715Z 08DD4D35366FD225]
Could you please help me resolve this issue? Is there any additional setting I need to change on my Outlook account to allow SMTP authentication?
Thank you for your assistance.
Best regards,
