My original account was hijacked a year ago and my email associated with that account was...

You're right, we can only speculate.
Sadly if it's not possible to access to the account you may need to purchase again the game with a new or different account.

A good way to avoid a similar situation in the future is protecting your account using the two verification factor and adding an authenticator app
Now I'm going to share a related article if maybe you didn't know about that feature:

To be honest it's hard to know what happened exactly to the account

I really wish to be able to assist you more on this one, but the help is limited

No, my account was created long before even considering buying Minecraft and when trying to log in there (that is, to account the game was purchased on) i'm prompted to log in to Microsoft account which I do not have access to. I have already sent out a recovery request but it was unable to verify me as the original owner of that account.

Hi, this is Manuela. I'm an Independent Advisor

If I understood correctly your concern, you created a Microsoft account to play Minecraft but now you're not able to access to that account?

If that's your case, may I know if you already try to recover the account using the possible solutions provided in this related thread?

As a reminder, please avoid sharing any kind of personal information. Here in the forums is not possible to review or check account information

I'm not sure either, we could only speculate - the account was hijacked some time ago (perhaps somewhen in the last year), the original email removed, different one added and password changed - the usual when account is hijacked (most likely due to having Minecraft premium - not any pirated launcher). Right now I cannot access what I paid for and I miss the money spent.
