The only thing I wanted to delete is (firstname.lastname@example.org) which was stolen 2-3 years ago. Trying to access my current (email@example.com) account I kept getting a window asking for verification for (firstname.lastname@example.org). Checking "I do not have this account", the next window asking for an email address so you could contact me. I used (email@example.com) and the window stated that the eMail could not be used since it was the sign in for Microsoft. firstname.lastname@example.org was merely set up as a temporary account to get into my eMail - this account will be also deleted. This is getting complicated.
