How come it doesn’t let me log in to my Microsoft account on psn

Hi,

have you tried to log in on the Microsoft website with your MS account ?

If that works you have to reach out for the PSN support.

I just bought Minecraft on my ps4 account and when I went to log in, it said that my Microsoft account is already connected to a PSN account. How do i unlink a Psn account from my Microsoft account

Yes

I play Minecraft on my PlayStation 4 so that's the console I'm having issues on. I'm not really sure what you mean by third party account as Microsoft only lets you link things to Microsoft approved/partnered things, but it was my Xbox/Microsoft account, I changed the Xbox account's randomly generated username to a new one and that's when I first started getting problems logging into my Microsoft account on the PlayStation but it still let me log back in eventually, then I changed my Xbox username to match my PSN username and now it doesn't let me log in at all.

I have this same error.

Except to my knowledge I have never linked my Microsoft account and PSN before trying to do so today. I only recently linked my Java edition minecraft to my Microsoft account, and today thought I'd try the Playstation version of the game. When I log into my microsoft account it says it is already connected to a different account.

How can I find out which Microsoft account has been linked to my PSN?

I play on PlayStation and the account that’s linked to it is deleted and still says log in with said deleted account

Unfortunately theres nothing that can be done about that because Sony only lets you link a single Microsoft account to your PSN for Minecraft.

Even if you could unlink the old Microsoft account, Sony wont let you link a different one.

The only option is to create a brand new PSN account and link a new Microsoft account to that.
