I dont have the account my playstation minecraft is linked to anymore, is it truly...

As the question states the account that my playstation minecraft is linked to doesn't exist anymore is it possible to have microsoft manually unlink them or playstation maybe because I have tried just about everything with no luck and Im at the point I dont think I will be able to play on realms anymore with my friends due to this issue. Really hoping this is a possibility

Unfortunately its not possible per

I'm afraid to say that's not possible to link a different Microsoft account with your PSN account besides the first you used
When you link accounts you can link and unlink the original one.

I would like to share an article where you can review this and more:

Hi Lucas,

I use two platforms, PlayStation 4 and iPhone with same Minecraft account.

And I linked same Minecraft to my PlayStation network.

Update, someone somehow removed my minecraft account from my microsoft account ??? I dont have minecraft anymore ??? Microsoft or whoever please help

When I logged out of my account on minecraft on my ps5 I forgot to unlink it. The email that I used on it is an old email which I don't use anymore. I can't remember what the email was. Since my old account is still linked, When I try to create a new account on it it doesn't work. What should I do?

You wont be able to link a different microsoft account. Youd have to continue using the old one.
