I forgot my Email and Username connected to my main minecraft account

Hi, my name is Courtney and I would be happy to help.

Let me understand a little more about the problem you are presenting, have you never migrated your Mojang account to Microsoft? Let's say that this obligation is more than mandatory, since if it is not done, the accounts that were not migrated in the estimated time may be lost or perhaps eliminated.

Please, if you would be so kind as to offer me more details about the problem you are presenting, I could offer you better help and perhaps a solution to resolve said problem.

I wait your answer.

Best regards,
Courtney.

I have the new Minecraft version on my PS4, and I logged into my main email account, it wasn't letting me play because of how my account is set up. So, I logged into my secondary email and I got a message "Oops! Looks like this account is already connected.
Please sign in with your previously connected Microsoft account, (My username)" It showed my old account username there. I have logged into that account, unlinked it, pressed the clear account sign in data button (which doesn't seem to do anything) but I still
get the same error every time. Any help would be greatly appreciated

Ok so I found out that I didn’t buy the Minecraft in this account but on another. I switched from my Xbox 360 to my new Xbox One S. But this account got locked until like March 1st 2021 so I made a new one. With my sons name and my name. But I removed the account from the Xbox and signed in with the old one. But Minecraft still worked. So I deleted it. But when I wanted to redownload it. It wasn’t free. Also I forgot the username of the account and this account and the other one are both tied to the same email. Can I get the username back with the email?

so the problem kinda is that I did not forgot my email. mojang made a new email for my minecraft account.

my minecraft account is linked to a email I don't know the existence off

I'm sorry, I remember my username, but I forgot my email used for the account, hope you can help with the provided information above.
