Login Credentials Expired?

when trying to type the msg above including the emails it gave me a html error so i had to remove them but when i mention main xbox account its mailto:[edit: email address removed] and then when i mention main email linked to my microsoft account its mailto:[edit: email address removed] but when mention the account that got linked to my account and the verification code gets sent to is mailto:[edit: email address removed] and when typing that in to a reverse email lookup it comes out as mailto:[edit: email address removed] so idk which one is right maybe @stomatom.com is what hackers use
