Does anyone know how to disconnect a Microsoft account from Playstation if you don't...

Hey amirhossein, sorry you're having trouble! I'm here to help clarify.

The only way to remove or unlink a Microsoft account from your PlayStation is by going into your PlayStation account settings. Microsoft does not control the linking on the PlayStation side, so you cannot remove it from your Microsoft account directly. You may need to contact PlayStation Support to help unlink the Microsoft account from your PSN account.

I hope this helps you! Let me know if you have any other questions.

Does anyone know how much the PSN subs will be for the PlayStation 4?

There is a Microsoft account logged it to my ps4 account that I don't know the login details of and I disconnected it from my account but it says I can only use that one not connect a different one can someone help because if this is a rule for ps4 Microsoft account that's trash so I don't believe they would do that

I would think its more of a Microsoft thing (could be wrong) since this info comes from the minecraft (mojang) website and Microsoft owns Mojang:

Linking a Microsoft account to a Playstation® account

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. 

Never understood this thing about announcing you are going or might be going to the PS4.

Does anyone actually care if someone plays their games on the PS4 ? I know I don't.

Are the people who say this under the impression that someone from Microsoft is going to beg them not to buy a PlayStation?

Like I've always said,if you can then get both xbox & PlayStation,then you get to play on both consoles.

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.

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.

Note: As of March 15, 2023, please DO NOT unlink your MSA from your PlayStation account via the in-game menu. You will be unable to link it back if you do so.

This is a restriction imposed by Sony.
