Obtaining Microsoft account email for Minecraft

I've read the Microsoft section regarding forgotten emails and it seems there's no way to do anything about it (that I can tell anyway)...you either need to remember the email so you can recover the account or create a new MS account.

Hi JamesWeber3, I hope you're doing great out there despite the issue that you're experiencing. I am an Independent advisor and I am here to help you in regard to your concern.

You will be able to install Minecraft for Windows via Microsoft Store App. Make sure that you're signed in under the correct account where the game was purchased.

To clarify as well, sign in to https://account.microsoft.com/billing/orders using the Microsoft account that you used in purchasing Minecraft for Windows. Please note that Minecraft for Windows can't be obtained without a Microsoft account, you may have used your Gmail email address in signing up for Microsoft account so please check that.

the email for that account was dovietthang134@gmail if that's needed
Paid Minecraft, create a Microsoft account linked with that email dedicated to Minecraft
And now Microsoft just straight up telling me that account "doesn't exist" after a month of playing

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.

Hi so I did not buy minecraft on my minecraft account. I first made the account on a mojang account and then transfered it to microsoft so I was wondering if it was possible to move the linked microsoft email to my new email since the old one got closed.
