Unlink my Microsoft account from my Playstation account

I need to unlink my PlayStation Network account from my old Microsoft account which I don’t remember, & link it to a new Microsoft account to play Minecraft

You can unlink the psn account however you CANT link a different one.

Note: Once a Microsoft account has been linked to a PlayStation® account, neither the Microsoft account nor the PlayStation™ Network account can be associated with a different account. 

If you choose to unlink accounts, then purchases will be returned to the account which made the purchase. Even after unlinking, Microsoft and PlayStation® accounts can only be re-linked to the original account.

This is coming right from the Minecraft website

Hi,

Try unlinking your Microsoft account from PlayStation (if possible because I don't use it). you can also unlink 3rd party apps/sites (such as PlayStation) from your Microsoft account from here:

You mentioned on your post that "3 weeks ago i unlinked my main account from mc to log in an alt". How exactly have you unlinked your Microsoft account to login with an alternative account?

You played with both Microsoft accounts (main and alternative) using the same Playstation account?

I am attempting to connect my microsoft account with my Ps4 account. My microsoft account is already connected to a Ps4 minecraft account. How do I find what Minecraft account is using my microsoft account and to disconnect it from it.

Even if you could disconnect it you wont be able to link a different Microsoft account.

This is a restriction imposed by Sony.
