Can I change the email of only the Xbox account and not the entire Microsoft account?

The Microsoft account and the Xbox account are basically one in the same. They cannot be separated. One of you will have to start over fresh if you wish to use separate accounts.

the xbox account IS the microsoft account, the microsoft account covers all microsofts services.

Hi there,

the only thing you can change is the email address used to sign into a Microsoft Account (Xbox Live Account), this will only change the email address used to sign into the account. (It doesn't transfer the full Xbox Live Account to a different Microsoft
Account)

The steps to change the email address can be found here:

Changing gamertags, will only result in a different gamertag, it does not change the account or take any save game progress with it.

Is the change sign-ing email address option what you seek or do you want to achieve something else?

Hi, you can only change the email of your Microsoft account, that will then change the email for any of the services that are associated with your account (XBOX, Office, Windows, etc, etc) https://support.xbox.com/en-GB/my-account/microsoft-account/change-email-sign-in-for-microsoft-account

Many thanks Brad,

Does that make the Microsoft email deleted and not just the Microsoft Account? I was under the impression that the only way you can delete a Microsoft Email and Skype service for example is by deleting the entire Microsoft account.

The problem is this will delete Xbox Live account as well. This is why I was thinking whether changing the Xbox Live Gamertag profile alias to another primary email such as Gmail, Yahoo, etc and then deleting the Microsoft Account will not erase the Xbox Live
profile? Or will that go away too?

Also I thought there was a 60 day window period if in case you were to delete an email or MS account if you log back in the deletion process will be reverted. But no where does it say that you can keep Xbox Live account but be able to delete Microsoft account
alongside the Microsoft email. This is where I am getting confused.
