Link Xbox’s

Hello, JOHN. Thanks for reaching out! My name is Lucas, and I'm an Independent Advisor and a Microsoft user just like you. I'll be happy to assist you today.

So you want to share your game pass ultimate subscription with your son, right?

Are you connected simultaneously with only one account or each one of you have your own account?

Hi,

Ok,

Your profile with us it's fine as I read.

Your connection experience lag (for help with this try https://support.xbox.com/en-US/xbox-360/networking/slow-performance-solution)

Your GT linked to Epic, then you need to contact epic for help (http://launcherhelp.epicgames.com/customer/en/portal/articles/2915240-when-i-try-to-link-my-psn-xbl-account-to-my-epic-account-it-says-that-my-psn-xbl-account-is-already-linked-to-an-epic-account-)

Hope it helps.

Also what your doing is considered marketplace theft and could get you and your friend permanently banned if caught. The 'home' xbox feature is meant for sharing games and gold accross xbox one systems that YOU own. NOT with friends.

So id stop trying to share your games with your friend all together as youd also lose all you accounts content without refund if it gets permanently banned (i.e. dlc,games,remaining gold membership, remaining marketplace currency)

What are some specific examples of marketplace theft?

Marketplace theft includes, but isn’t limited to:

Getting, asking for, or using redemption codes illegitimately

Transferring licenses to your console from an account that you didn’t create

Using a system glitch or loophole for financial gain

Using any sort of “shared” account to avoid having to pay for games or content

Successfully redeeming or giving away a code and contacting customer support claiming the code didn’t work

Attempting to defraud Microsoft or authorized agents

Fraudulently transferring content licenses

Sharing account credentials

Asking to be added to someone’s third party subscription (such as Netflix, Hulu, etc.), in order to avoid restrictions or payment

CONSEQUENCES

A violation of the Microsoft Code of Conduct may be cause for these or other actions:

• Automatic assignment of a new Gamertag, if you create an inappropriate Gamertag.
  
• Content deletion, if you create or use inappropriate Content.
• Restrictions (e.g., communications, multiplayer, account access) on your use of Xbox Live services, if you abuse those services.
  
• Permanent suspension or device ban, if you commit an egregious violation that includes, but is not limited to: hacking, modding, profile tampering, fraud, trading or stealing accounts or Gamertags, severe racial remarks, impersonating Xbox staff, displaying
  nudity, repeatedly creating inappropriate Gamertags or profile content, distributing URLs to phishing sites.
  
• Permanent suspension or device ban, if you try to avoid suspension with alternate accounts and/or devices.
  
• Permanent suspension or device ban, if you repeatedly commit violations.

UPON RECEIVING A PERMANENT SUSPENSION, YOU FORFEIT ALL CONTENT LICENSES, GOLD MEMBERSHIP TIME, AND MICROSOFT ACCOUNT BALANCES ASSOCIATED WITH THE SUSPENDED ACCOUNT.

Microsoft accounts (regardless of the email host you use) are what are used to log into an Xbox account.

If your Xbox Account is an offline account (which on the 360 the ability to create a local account was possible), you would need to make that offline account an online account by using the Microsoft account (provided it's not already tied to an Xbox gamertag.
Those steps can be found
here.

If the Xbox account is already an online account with Microsoft account attached to it, then no, you will not be able to merge the 2 accounts together. Nothing can be transferred between accounts so any rewards earned on one account are locked to that account.

I hope they can give you a solution, I am waiting for the result.

Thank you for your kindness and understanding! Please feel free to let me know if you need anything else.
