There are several ways to log in:

1.
User/Primary password (MFA must be turned off for the account).

Remember to turn IMAP, POP3 on:

I’ve tried all of the steps and still facing the same issue

You need to be more specific. Which scenario you try to accomplish? I suggest using App passwords.

You can contact us directly - you can find support email in the footer.

I did 1 and 2 both ways and getting same issue for imap and pop3

We'd need more details to help you: screen-shots, your code, do you have MFA turned on?), otherwise I suggest contacting your server administrator for help.

I've just check and have no problems connecting and authenticating - both using app passwords and primary password.
