If I understand the chain of events, I would suggest deleting the two emails. I would also strongly suggest against trying to log into accounts, which you haven't created yourself.
I recently replied to a post, which should also be of help to you. Please make sure to change your Hotmail password and secret question.
Best of luck..
Today I opened the hotmail login and when i began to enter my email there are two emails that popped up "firstname.lastname@example.org and email@example.com" (M is my first initial and Kloster is my last name) but I've never had emails such as this. At that point I attempted to login to both of these accounts and when i go to "forgot password" they send the "change password" emails to each other (must be linked). My question is this: Have I been hacked? Has something like this ever happened to someone else?
