Adding 2nd outlook accound

Hello, I started using Thunderbird in order to be able to manage all my email accounts from one place and I stumbled to one problem. I have 6 different email accounts and all are created by me. I know that I cannot add a Proton account as it requires a paid service from Proton that I don't need as I use it only as a backup account in order to be able to recover the other 5 ones. My Yahoo account added successfully without any problems as my 2 Google ones. My primary outlook was added successfully by using the simple add account setup. The problem started when I was trying to add my second outlook account. Everything I tried it always gives me an error that says "Authentication error. Unable to login at server. Probably wrong configuration , username or password." I know for a fact that the username and password are correct as when I start to add the account it displays a prompt on my phone to verify the connection. But at the last step it says the error I mentioned. I even tried to clear all cookies and passwords and tries again but without any success. I compared the configuration of the 1st outlook one to the 2nd and they were correct. Correct hostnames, security etc. I also checked the account settings in of the emails on the providers page and the only difference is that in the 2nd I haven't enabled the 2FF authentication. What am I doing wrong? Appreciate the help! Alex
