Send email nodemailer from Outlook365 erro [duplicate]

Question

I'm using the firebase function to trigger the nodemailer and send an email.

Using gmail I was successful, however with Outlook365 it does not work.

My transporter

var transporter = nodemailer.createTransport(smtpTransport({
host: 'outlook.office365.com',
port: 25,
secure: true, // use TLS
auth: {
    user: 'myuser',
    pass: 'pass'
},
tls: {
    // do not fail on invalid certs
    rejectUnauthorized: false
}}));

I have tried other ports, using the service: "Outlook365", but I did not succeed.

The console always returns me the following error

Error: getaddrinfo ENOTFOUND outlook.office365.com outlook.office365.com:587
at errnoException (dns.js:28:10)
at GetAddrInfoReqWrap.onlookup [as oncomplete] (dns.js:76:26)
code: 'ECONNECTION',
errno: 'ENOTFOUND',
syscall: 'getaddrinfo',
hostname: 'outlook.office365.com',
host: 'outlook.office365.com',
port: 587,
command: 'CONN

thank's

Answer 1

IMAP (incoming) -> outlook.office365.com -> Port 993 -> SSL

SMTP (outgoing) -> smtp.office365.com -> Port: 587 -> TLS

I think you have port configuration error look again into this. For more you can refer, Configuring Your Email Client for Office 365
