Email Sender fails with error: Basic Authentication is not supported anymore

Greetings community,

I recently noticed that all my email sender nodes are failing. The error reads as such: Execute failed: This error occurred while communicating with the SMTP server: "javax.mail.AuthenticationFailedException: 535 5.7.139 Authentication unsuccessful, basic authentication is disabled.

In my case I was using Outlook smtp with the port 587 using STARTTLS. I have basic password as well as an app password, but the same error appears regardless.

I found a post from oracle indicating that basic auth is going to be deactivated and oauth2 should be used instead. How could we use oauth2 in the email sender nodes?

Hello @pharawer,

Welcome to the community!

I would take a look at this thread specifically, if this is not possible, I will get in touch with one the devs to find out more information on it.
