Microsoft account is already linked to another psn account.

Hi Pedri G! I hope you are well, delighted to be able to offer you my help!

I'm sorry you're in this situation.

The solution is to link your PSN ID to another Microsoft account, because the
The Microsoft account you are trying to use is already linked to another PSN ID.
Each Microsoft account can only be linked to one PSN ID and vice versa.

Note: If a Microsoft account is linked to a PlayStation account, neither the
Microsoft account nor the PlayStation Network account can be linked to other
accounts.

Best regards,
Daniel.

In this case, your Playstation account is already linked to another Microsoft account. You would need to find out what Microsoft account it is and sign in with it. Once you link a Microsoft account to a Playstation account, neither the Microsoft nor the Playstation account can be linked to another Microsoft/PSN account.

But how can be linked on different PSN ? It doesnt make sense .I have only one psn account and i cant use another microsoft account because i dont have another one . If i use mobile number or e-mail i cant because it is already link with microsoft.

Hello!

My name is Dérek, I'm an independent platform consultant and I'm grateful for the opportunity to help you.

Annie, following your report, as the error is in the linked account, Sony will not be able to help you either.

Neither Sony nor Microsoft has access to the linking system, as the system is owned by the game's developer, in this case Mojang.

This in all games, such as fortnite, EA games, UBISOFT, no platform has access to this link system, all are the responsibility of the developer.

So only mojang can manage this link, try to explain it in a very detailed way, asking them to manage this account link.

I remain at your disposal if you have any further questions.

it can only be done on psn side as it is connected to their system, but once a microsoft account is linked to a psn account it cannot be linked to another.
