I have trouble logging in

If your Minecraft account was migrated to a Microsoft account, what happens to your Microsoft account applies to your Minecraft account. Therefore, you should recover your Microsoft account in order to access your Minecraft game again. As mentioned above, try to recover your account using the other email address you saw it there. That could be the email address that's currently attached to your main account.

When was the last time you were able to access your account? If it was just recently, there's no way your account was deleted or closed because it will take 60 days to close an account. Since it asked you to create a new account with your original email address, that only means that your email address was removed from your original account and was replaced with a different one by someone.

To start the recovery, you should know the current email address attached to your main account. You will need it in filling out the recovery tools online such as https://account.live.com/pw and https://account.live.com/acsr.

I am afraid that you cannot request a refund if you don't have full access to the account.

So it's a whole new account with a different Xbox profile or gamertag, correct?

Do you know the full email address of a different email you mentioned above? I am afraid that someone has taken over your account.

If you knew the current email (the different one) of your account, you may try to reset the account password through https://account.live.com/pw
***Make sure to sign out any account signed in to https://account.microsoft.com website before starting an account recovery.

If it doesn’t work, try to fill out the account recovery form on https://account.live.com/acsr

You may also use the Microsoft’s interactive tool here https://support.microsoft.com/account-billing/h...

it allows me to login on my original account, but it also gives the option to log into my account using a different email address that is not mine. I receive this code whenever I try to use a Microsoft application. I've tried looking for this other email on settings, but I can't find it anywhere as either an alias or some other account.

The account closure can take up to 60 days before it gets completely deleted. Your email address must have been removed.

Do not use your original email address, use the different one. Try to sign in or recover it via https://account.microsoft.com website
