Email Cracking advice

[Lurker]

I have been working on cracking an outlook account with no success. The account is not in any data breaches/leaks, phishing and google dorks has not really worked for me. I have looked into a couple of brute force options but am concerned about locking the account, I recently locked a hotmail. There is no 2FA.
Have tried using dumpsterdiver, hacker_dk, johntheripper, sherlock in python on windows
Any advice about next steps or if this is an impossible task
Any comments are appreciated. Thank you.
