New account access

I will still be using the same Xbox, just a new account. I can play all those game whilst logged into my new account?

As long as the console is set as the Home console for the old account, yes.

Nothing can be transferred between accounts. If you're using the One, Series S/X you can still access the games if you have the console set as your Home console for the old account.

I'm not entirely clear, but let me ask.

Are you saying you lost access to your original account, and made a new account?

If so, any purchases from old account will not be available to new account. To access these, you would need to recover your old account.

I have access to the Microsoft account its the xbox account that I don't have access too it just prompts me to make a new xbox account
