An xBox User Name showed up with my email

Ok, i changed a couple of settings on the website, so not 100% sure what one it was that allowed the subscriptions to show up on the xbox, in the settings, i changed the sharing "Add video to public playlist" to ticked, in playback i unticked "Keep all my
subscriptions private" and i changed my user name from my email back to my original user name of , some how as well, i also made my "channel" public, that created a Google+ account as well.

Im a hotmail user and an XBOX Live user with two different names. is different than my email name.

In order to guide you properly please share an screenshot about this email and the sender email (click on the name, some phishing emails shows the sender's name as an email to trick you), in that way I can tell you if it's real or not.

Hi XxSk33tSk33txXx,

The error code you are now getting be due to the following:

Problem
You see the following error code and message when you try to sign in to Xbox LIVE:



Account does not exist.

Status Code: 8015D002

This may mean there’s a problem with your account. For example, the security information for your account may need to be updated

Solutions

Solution 1: Did you recently sign up for two-step verification?



If you recently turned on two-step verification, you may not know how to sign in to apps or devices that don't accept security codes. Some apps (like the mail apps on some smartphones) and devices (like the Xbox 360) can't prompt you to enter a security proof
when you try to sign in. If you get an incorrect-password error with an app or device, you'll need to create a unique app password to sign in. After you sign in with your app password, you're all set to use that app or device. You’ll use this new app password
to sign in to your device instead of using your Microsoft account password.

You'll need to create and sign in with an app password once for each app or device that can't prompt you for a security proof.

1. Sign in to your Microsoft account.
   
2. Under Password and security info, tap or click Edit security info.
   
   If you're prompted for a security proof, enter it and tap or click Submit.
3. Under App passwords, tap or click Create a new app password.
   
   A new app password is generated and appears on your screen.
4. When you’re prompted for your Microsoft account password on your Xbox console, enter the app password that you created online.
   After you sign in with your app password, you're all set to use that app or device. You will use this new app password to sign in to your device instead of your Microsoft account password.
   

Solution 2: Verify your Microsoft account security information
Follow these steps:

1. Visit Microsoft account.
   
   Note If you forgot your password or can’t sign in using your password,
   reset your password.
2. Click Edit security info.
3. Verify your security information. For example, verify the Phone number,
   Alternate email address, and Security question information.
4. Sign out of your Microsoft account and then sign in again.
5. Try to sign in to Xbox LIVE again.

Solution 3: Delete and re-download your Xbox LIVE profile

1. When prompted to confirm storage device maintenance, select Yes.

I appreciate all the suggestions, I'm still working on it but haven't found the solution. I'm about to clear my cache now.

When I use this Gamertag without getting on Xbox Live I cannot click on "Account Security" because it is like greyed out. Like it's not available.

It's still really frustrating, and I appreciate everything guys. I'm gonna clear my cache now, wish me luck.
