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