Primary Email:

Hi there. My name is Ron, I'm an independent advisor. I will be more than happy to help you.

When changing the primary alias of your account, it should work right away but it takes 48 hours for the change to be implemented across all Microsoft services. Please try using a different device or a different browser to change it and see if it works.

Thank you for a quick response wi7bit

Hi ArthurHarris1

The only way around this is give your son your old Microsoft account and create a new one for yourself and transfer your emails over.

Even if you create a new email alias on the old account, the content is still linked to this account and can still be accessed through his Xbox.

Please note, email aliases cannot be transferred between account. So won't be able to add the old alias to the new account. Even if you do change it.

Hi! I'm Rostom, an Independent Advisor. I will be glad to help you here.

Do you have access to both accounts?

You need to have access to those two accounts to perform the steps. Please note that it is only applicable if your main email address is a 3rd party email address and is not a Microsoft email address. We cannot transfer a Microsoft email address from one account to another.

If that was 3rd party, you have to sign it in via https://account.microsoft.com/ > Your info > Edit account info. You have to add a new email address to free up your main email address so you can add it to your current Xbox account.

There is a process to change the primary email on a Microsoft account.

First add it as an alias do not make it primary. Make sure it works correctly to sign in. Promote that email to primary and again validate. Last remove the former primary address from the account.

You can search on how to change primary email on MS account and should find a step by step guide.
