Unlink my Microsoft Account with Xbox one

It sounds like there's some kind of confusion between Skype accounts and Microsoft accounts. Sign in to Skype on the web with to unlink your accounts, and then you can re-launch Skype on Xbox One to link the Skype account you want to the Microsoft account
that you use on your Xbox.

(For more information about unlinking accounts, see

But there's no way to unlink my XBOX account from a Microsoft account without creating a new Microsoft account?

It's not that I don't have access to my Microsoft account. The fact that I can't unlink my Microsoft account that's connected to something that I can't unlink without knowing where to start.

I don’t know what email I used to link to my PS5 for Minecraft account. Could somebody unlink the account connected to my minecraft account if not can you tell me what email is linked to my minecraft account. Would I have to go to PlayStation to get it unlinked or do I go to Microsoft since it’s the accounts that are needed.

Even if you could unlink the account you wouldnt be able to link a different one.

Per https://help.minecraft.net/hc/en-us/articles/360037725571-Minecraft-for-PlayStation-FAQ

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 a Sony imposed restriction, not Microsoft/Xbox.
