Nodemailer and Godaddy, I've tried every solution to no avail - node.js

Question

I bought a domain and an email adrees with GoDaddy with Office 365 Basic bundled with it.
I'm trying from a few days to send just an email with nodemailer from my node app without ever succeding because I always get a 535 Authentication Failed from user#domain.com.
I've scanned StackOverflow for days trying every solution, this is every setting I've tried to pass to nodemailer.createTransport:
const mailerConfig =
{
//First set of parameters tried
service: 'Godaddy',
host: "smtp.office365.com",
secureConnection: true,
port: 587,
auth:
{
user: "user#domain.com",
pass: "password"
}
//Second set of parameters tried
host: "smtp.office365.com",
secureConnection: false,
port: "587",
auth:
{
user : "user#domain.com",
pass : "password"
},
tls:
{
ciphers:'SSLv3'
}
//Third set of parameters tried
service: "outlook",
auth:
{
user: 'user#domain.com',
pass: 'password'
}
}
None of these three settings worked, someone has any idea?
Thanks.

Answer 1

There is a godaddy FAQ entry called "Manually configure email set up on Thunderbird" (which seems to be only accessible via WaybackMachine).
It mentions the following configuration:
Incoming (IMAP): imap.secureserver.net 993 SSL Normal password
Outgoing (SMTP): smtpout.secureserver.net 465,587 SSL Normal password
and
Username: Workspace Email address
Using the above, especially smtpout.secureserver.net as SMTP Host works for me – tested with godaddy email in 2021.

If anyone is still having issues, this config is working for me actually in Sept 2021:
var transporter = nodemailer.createTransport({
host: "smtpout.secureserver.net",
port: 587, // port for secure SMTP
auth: {
user: "youremailaddress",
pass: "yourpassword",
},
});

You need to enable all access
and don't forget to disable the sms/call confirmation for the login
by the way this code i used on firebase cloud function/nodemailer
cors(req, res, async () => {
var transporter = nodemailer.createTransport({
host: "smtp.office365.com",
port: 587, // port for secure SMTP
auth: {
user: "user#domain.com",
pass: "password",
},
tls: {
ciphers: 'SSLv3'
}
});
if (req.method === 'POST') {
var mailOptions = {
from:req.body.from,
to: req.body.email, // list of receivers
subject: req.body.subject, // Subject line
text: req.body.text,
};
return transporter.sendMail(mailOptions).then(() => {
res.status(200).send('Email has been sent to mr/ms : ' + req.body.email); return ("mail sent")
});
}
})

You must enable SMTP login for the O365 mailbox or user in the admin settings
If the user has multifactor turned on, then you need to use "app password", normal password won't work if MFA is enabled.

You need to disable security defaults or adjust Conditional Access policies.

Also, you can debug issue using sign-in logs in azure user account.
