Outlook SMTP authentication on n8n fails after enabling IMAP/POP, two-step verification, and setting an app password. Authentication errors persist. Guidance on adjusting Outlook settings is needed.
hey, i had a similar truble. reverify your smtp port & encryption, sometimes outlook keeps an old pass cached. try resetting app password in outlook again and reconfigure n8n settings.
In my own experience, resolving similar issues required a careful review of settings beyond just the app password. I discovered that Outlook sometimes imposes additional security measures on unfamiliar sign-ins, so checking the account’s recent activity for blocked attempts could reveal clues. It helped to review the detailed configuration in both Outlook and n8n, specifically around the TLS/SSL settings. Verifying that the n8n configuration completely reflects the security updates also proved vital. A methodical approach, examining all security logs on both sides, was instrumental in pinpointing and solving the problem.
I encountered a similar headache with Outlook and n8n some time ago. I realized that Outlook might treat app passwords differently when their security system identifies what it perceives as unusual logins. In my case, I double-checked my mail server settings and ensured that the encryption method was compatible. It was also useful to temporarily disable two-step verification, test with a new app password, then reenable security features once I confirmed that the server was accepting the credentials. Additionally, examining any sign-in notifications in Outlook helped pinpoint and eventually resolve the issue.
