Yes that’s exactly what I did . By the different way I meant : I directly changed the user and pass as they are , just to test. I made a simple one repo just to test : GitHub - cz101/nodemailer: A simple mailer test for third party smtp Netlify site : brave-mirzakhani-44b160 Chao

There is no such firewall or blocking of requests that I am aware of. I have Nodemailer running (not using Outlook) and have no issues. Searching for Error: Invalid login: 535 5.7.3 Authentication unsuccessful ( see results ) I found: https://answers.microsoft.com/en-us/msoffice/forum/all/535-573-au…

Got it . Thanks for everything btw! :slight_smile:
