Is that possible?
If both are linked and use the same login: No.
Why shouldn't that work? Skype is Skype. If you go to the Skype page and delete that. I don't know the xbox now. But you do not believe that you press delete on skype and delete something on Microsoft. Then delete whatsapp would be synonymous with deleting Facebook, just because the company offers both services. Explain to me how it works with skype. Or whether there's something special about xbox.
But you do not believe that you press delete on skype and delete something on Microsoft
yes, because that's the way it is. When you delete the Skype account, you delete your Microsoft account
Because your Skype account is a Microsoft account… The login is the same, the account behind it is the same. If SeppelLP has now used the same account for Xbox and Skype, it is also the same account when using it - which is why it can't be separated and can't be deleted separately.
