Mailing programatically through Microsoft account

Question

We have created an email in our account (Microsoft) to send mails programmatically. The mail is of the type npreply@...

How can I send mails programmatically, in order to inform the suppliers of the integration of data, with python smtplib.

My code is:

with SMTP(Connection["Server"],Connection["Port"]) as conn:
conn.ehlo()
conn.starttls()
conn.ehlo()
conn.login(Connection["User"],Connection["Password"])

conn.sendmail(Connection["User"],AllAddrs,msg.as_string())  

print("Message sent!")  

Where Connection["Server"] indicates our MX endpoint and port is 25. User is the noreply@....

This gives error:

line 697, in login
"SMTP AUTH extension not supported by server.")
smtplib.SMTPNotSupportedError: SMTP AUTH extension not supported by server.

Answer 1

Basic Auth is now disabled in most tenants.
Also, if you're connecting to office 365, the smtp for client submission runs on port 587.

Answer 2

So @Rafael da Rocha , what should I do?

Connect through port 587 and run the same sequence of commands?

Where may I find a snippet of code in python (or not)?

Thanks
