contrib-email-out,

Is there a reason you are not using the email node supplied by the node-red developers, which is the one most people use? That is node-red-node-email.

If you look at the github page for the contrib node you will see that it has not been updated in four years and there are outstanding unaddressed issues dating back to 2017. I suggest you uninstall that one and use the usual one.

I had an old hotmail account and I tried the office365 settings with the node-red-node-email
and it also fails with the same error when i have "Use secure connection" checked.

If i unckeck it the email goes through.
TLS checked

If, with the standard email node, you attach to it a Catch node and a Complete node, then the Complete node will fire on success and the Catch node will fire on failure.

Office 365 uses "modern authentication" and so will fail if you don't connect using OAuth or similar if modern auth has been required (which it should be if you follow the Microsoft recommended security baseline). Further more, if your admins have turned on MFA, you will need to create an application password and use that instead of your normal login. This may or may not be possible depending on how O365 is configured and what rights your user-id has.

You should contact your O365 admin team to get some help.
