What is my Microsoft email for my Playstation account?

Account connection happens on the PlayStation servers. Only their support can deal with it

I have the same problem. But am on playstation 4. It cannot get past the email screen even when the email I put in is linked to an EA account. The EA account email is not the same as the email that my account with Playstation Plus is linked with. What can I do?

I don’t know what email I used to link to my PS5 for Minecraft account. Could somebody unlink the account connected to my minecraft account if not can you tell me what email is linked to my minecraft account. Would I have to go to PlayStation to get it unlinked or do I go to Microsoft since it’s the accounts that are needed.

Even if you could unlink the account you wouldnt be able to link a different one.

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.

This is a Sony imposed restriction, not Microsoft/Xbox.

Could it be that in my PlayStation I have another email and password and in Microsoft account diferent email and password than the one I put when I installed my PS??

Sony does not allow you to unlink a Microsoft account, your issues are with them.
