imaplib.error: b'LOGIN failed' when trying to login using imaplib in python

Question

Good day, I am trying to use imaplib to connect to exchange server. Below is the code:

import imaplib

imap_host = 'example.smth.smth.kz'
mail_login = 'name.lastname@smth.kz'
mail_pass = '**********'


M = imaplib.IMAP4_SSL(imap_host)
print(M.welcome)
M.login(user1, imap_pass)

M.Welcome returns b'* OK The Microsoft Exchange IMAP4 service is ready.' , which means that I was able to connect to the server. However, when I try to log in I got this error: imaplib.error: b'LOGIN failed' Altough, credentials are correct. What is the issue here?

Answer 1

Your mail login username and password are incorrect according to your imap4 mail host.

When I look at your code, there is no user1 and imap_pass variable. If you want to write your given code correctly it should look like this:

import imaplib

imap_host = 'example.smth.smth.kz'
mail_login = 'name.lastname@smth.kz'
mail_pass = '**********'


M = imaplib.IMAP4_SSL(imap_host)
print(M.welcome)
M.login(mail_login, mail_pass)

Maybe use getpass to prevent passwords in your code:

import imaplib
import getpass

imap_host = 'example.smth.smth.kz'
mail_login = input("Username: ")
mail_pass = getpass.getpass()

M = imaplib.IMAP4_SSL(imap_host)
print(M.welcome)
M.login(mail_login, mail_pass)
