Switching an email on an account to another email

Hi!

Yes, It is possible.

You will have to change the Email address associated with your brother's profile.

To do that please visit https://support.xbox.com/en-US/my-account/microsoft-account/change-email-sign-in-for-microsoft-accou... and follow
the instructions.

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.

This switching of login emails will only work if they are not Outlook, Live, or Hotmail.

See here how to switch email logins:

You will first need to change the email of the first account that has the email you want to a 3rd email and then about 48 hours later (may take up to 48 hours to sync across all systems) you can switch that email to the account you want it on.

For moving Gamertags, you will have to purchase a change on the account that has it and then that gamertag is freed up for use on another account to either take it for free while creating a new account or after you purchase another change on the other account.

If you delete the account, you loose everything associated with it. Including the email address.

You can't transfer one Microsoft Email address from one Microsoft Account to another. You can switch out email address if the email addresses are not Microsoft ones.

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