So today my hotmail decided that it was time for a checkup on my security concerning my mail. I was supposed to verify some password they've send to an old email of mine but the problem is, it seems that my old email no longer exist. This means that i cannot type in the password and therefore, my email is now unusable. Every time i log in to my normal email it keeps asking for this password and i cannot retrieve it. what am i supposed to do?
