Hit the process of registering a new outlook.com account, played with it and got a new (just for test) address, accidently hit the button changed it to my primary account, then found no way to switch back!!!
Somebody mentioned this to solve the problem, but it doesn’t work to me.
Still trying to dig in to find out proper solution, but if I fail maybe I will give up my old hotmail mail box.
Somebody (stupidly?) registered a Facebook account with my Hotmail E-Mail address and no matter whose fault it is, it became a live account without verifying the E-Mail address, and I started getting all sort of social event notifications.
So I went to Facebook and do a password retrieval through the E-Mail address, I cannot believe that even a unverified E-Mail address can be used as password recovery, so at last I successfully take over the account and shut it down.
I guess someone is crying now but if I didn’t do that I will be the one crying in the corner, I believe this is Facebook’s fault.
