Transferer un compte xbox sur un autre compte microsoft -[Translation - Transfer an xbox...

Unfortunately, that is the problem with allowing someone else to use your account. That information cannot be transferred to another account. Your son will need to create their own account to use on your Xbox console. Xbox's Home Gold feature will allow
your son to use your subscription on the single console you set as your account's "Home Xbox".

Translating to French, using bing.com/translate:

Malheureusement, c’est le problème avec ce qui permet quelqu'un d’autre d’utiliser votre compte. Ces informations ne peuvent être transférées vers un autre compte. Votre fils devra créer leur propre compte utiliser sur votre console Xbox. Fonction Home
or Xbox permettra votre fils utiliser votre abonnement sur la console unique vous définir comme "Home Xbox de votre compte ».

Non le compte créé ne supprimera pas un autre compte, il faut juste créer un compte avec une adresse email différente.

Cordialement,

Ok tank you just one last question. If i delete the alias of my main account (dad email). my dad can access to outlook? (sorry for my English)

Hello pirostheo game,

Thank you for keeping us updated. There is a way to manage the email addresses of each Microsoft account. You must first remove the email that you want to use as

the primary alias. Once the primary alias on the Microsoft account has been changed, you can use the email address that you want on a different Microsoft account. The main reason you have to take this step is because you cannot have the same primary alias
for two different Microsoft accounts. It's basically just moving an email address from one Microsoft account to another. The article we provided contains steps on how to change the primary alias. You must do these steps for both accounts. Be sure to let us
know the results!
