Alright this is my second account. so every time i try to log in halo waypoint i get this message saying they are over protective and need to confirm my email… the thing is i can’t

year ago or two i tried to recover my account at a friends house and it says i need to change my microsoft email and i was a dumb yoink and put in an extra number Ex: (old)Ilikecookies@yoink.com (new i put in) Ilikecookies123@yoink.com
Note this is not my real ones just an example.

So everytime i log in to xbox live or recover my account i use the new one but i can’t access to the email cuz its not real

I suggest changing the Microsoft Account associated with your Gamertag to a new email, that you do know and have access to.

and i would change it on xbox.com?

any help plz?
