I’m locked out of my Xbox account because I forgot the password to the Microsoft account linked to it, and after too many failed attempts the account is now blocked/locked. The email attached to the account was originally my dad’s email, which I no longer have access to. I’ve tried the Microsoft account recovery form multiple times, but I keep failing it because I don’t know enough of the recovery information. I still know the gamertag and have used the account on my Xbox for years. I was wondering if there’s any alternative way to recover the account or if anyone has been in a similar situation before? Any help would be very much appreciated, thanks.
