Switching emails on Microsoft account

Hello S,

Thank you for contacting us! We hear you and we will be happy to help you.

According to your description, I understand that you want to switching emails on Microsoft account. Let me help you in this

Here I'm suggesting some steps to resolve this.

1. Sign in to Microsoft account | Sign In or Create Your Account Today – Microsoft using your current credentials.
   
2. Go to Your Info and select Manage sign-in methods.
   
3. Click Add alias and enter your son's email.
   
4. Verify the new email when prompted.
   
5. Once verified, set his email as the primary alias.
   
6. You can then remove your email from the account. (Note: you can't set alias this account again and you can't make a new Microsoft account from this email address)
   

I hope this information will help you solve your problem. If it is useful for your problem, mark it as useful or useless so that it can be useful to others.

Thank you for your patience and understanding

Best regards,

Unfortunately this is not possible and since your email is a Microsoft email (Live, Hotmail or Outlook) you can't switch the email to another one and have the account not be connected to that email anymore, technically.

You can switch the login emails around but you CAN'T switch TO a Microsoft email when you do this (Live, Hotmail or Outlook). You can switch to another email provider but you can't switch between Microsoft emails as they're permanently connected to that
account they were created on. For example, you can't switch this account's email login to another Microsoft account because that email is attached to a Microsoft account already.

The only solution is to start over and have him create a new account and have the account that owns all the games to be set as the my home xbox account on the xbox one so that the new account can play all the games that account owns BUT the saves and any
progress will not move over and some DLC will not share, also.

Also, once you have both email addresses, there is a way to switch them to the correct email. Use this a reference ..

Switch a gamertag to another Microsoft account ->
support.xbox.com/.../switch-gamertag-to-different-microsoft-account

Hi there, if you have two gamertags associated with the same email you will need to sign in as one of the gamertags on the Xbox and switch it to a different Microsoft Account (email) using the steps here:

support.xbox.com/.../switch-gamertag-to-different-microsoft-account

You can switch email addresses between the accounts only if they are not Hotmail, Outlook or Live emails. You can NOT switch gamertags between Microsoft accounts in any way.

See here to change emails around: NOTE that you will have to change the email of the first account to something else in order to free it up for use to change to the other account:
