When I sign in to Microsoft Bell, two e-mail addresses appear in a pop-up box. The top e-mail address is correct. I have an account in that name which I can access with it and I can get to my e-mail with it. The bottom e-mail address is misspelled (it ends with "@bell.nnet". It is not a legitimate Microsoft account, so I can not "Sign in" to close it. How can I delete this misspelled address from the pop-up box?
