You can only link one account:

"Linking a Microsoft account to a PSN account is on a title-by-title basis and permanent. Players have the ability to unlink the Microsoft account to that PSN account, for Forza Horizon 5, but will be constrained to relinking to only that specific and originally linked, Microsoft account"

Hi pouyan,

Thank you for posting in Microsoft Xbox Community. I understand that you want to inquire about unlinking a Forza Horizon 5 account from your PlayStation 5.

According to Forza Horizon's FAQ, linking a Microsoft account to a PSN account is on a title-by-title basis and permanent. Players have the ability to unlink the Microsoft account to that PSN account, for Forza Horizon 5, but will be constrained to relinking to only that specific and originally linked, Microsoft account.

Here's the official support FAQ page for your reference:

You can't do anything...once it's linked, it can't be changed:

"Linking a Microsoft account to a PSN account is on a title-by-title basis and permanent. Players have the ability to unlink the Microsoft account to that PSN account, for Forza Horizon 5, but will be constrained to relinking to only that specific and originally linked, Microsoft account."

once linked it is forever, you can unlink but only re link to the same account, this is a sony requirement, nothing can be done.

All of my Microsoft and Xbox games are downloaded on my external drive including the previous Horizon, which is Forza Horizon 4. I changed where new apps are stored when downloaded from the Microsoft store to my external drive but it still wont download Forza Horizon 5 to my external drive. On the Xbox app it wont show my external drive as an option to download to. I am able to download any game from the Microsoft store and Xbox app to my external drive except Forza Horizon 5.
