I suspect that a temp email service was used to lock me out of my email account and I want to find a way to access that temp account. I lost access to my Outlook account at least 2 years ago and anytime I try to log into it or Xbox live im told I need to verify the account. I then go on to fill out the forms that they send me too but they never work. I keep seeing that the recovery account was changed from the Gmail I use to "nx*****@exelica.com". I think this is a temp email service and was wondering if there was anyway I could access the "nx*****@exelica.com" account so that I could retrieve my old outlook account? Sorry if this isn't the appropriate sub for this kind of question but any information or advice would be greatly appreciated.
