Why is it that my account 'doesn't exist' when I try to sign into microsoft.com?

(I mean I said to do this but ok, sure. Overshadow my post)
I hate it when people do this

Hi there Thisal R,

I am Lumie and I would love to assist you today.

I am so sorry you are having issues with a compromised account.

The first idea is to use your phone number to directly log in as an alias.

You could also try to find your new alias here: [https://account.live.com/username/recover]

If none of this works, you can look for you should look for clients that may update like PC Minecraft.

Once you do this, you can recover your account from here: [https://account.live.com/acsr]

Detailed steps on how to use the Account Recovery Form can be found here: https://support.microsoft.com/office/b19c02d1-a782-dee6-93c3-dc8113b20c42

Microsoft takes account security very seriously, that's why Account Recovery is an automated process with no human influence. If you don't have the correct information, you may not be able to get through account verification using the Recovery Form.

The Account Recovery Form requires adequate information to prove that you are the owner of the account. The Account Recovery Process can be a time consuming process, but providing as much info as possible from the start of the process will increase the possibility of being verified by the automated process. You'll need to keep trying until you're verified by Microsoft.

Remember to use a familiar device from which you've frequently accessed your Microsoft account, as well as a familiar location. Microsoft will review your responses and respond within 24 hours. If you are verified, instructions on how to log back into your account will be sent to you, and if you are not verified, you will need to submit the Account Recovery form again. You can do this up to 2 times every 24 hours.

It's important to note that Microsoft Support will not be able to grant you access to your account, you will be sent back to the Account Recovery pages that have been linked above.

If your Microsoft account recovery request was not granted or was unsuccessful, please click the attached link for more information: https://support.microsoft.com/office/dc56c3e3-dff0-4ed5-8edb-60290eea6b53

I hope this helps.

I shall be here for your response. -Lumie

That first prompt appears, but when I try to sign in to my Microsoft account, it says it doesn't exist.

Im pretty sure its deleted because thats what other microsoft posts said about the same thing, but it still says it exists when i try to sign into my xbox account but when i try to sign into microsoft it says it doesn't exist and doesn't allow me to make another one?
