Managing personal Outlook.com account settings, security, and privacy
Hello LBell_217
Those emails would be generated anytime <anyone> clicks on "Forgot Password?"
There is no way to stop those messages since it would also prevent you from changing your password using the same option.
What I would keep tabs on are any unexpected successful logins to your account since if you see that, means someone was successful in hacking your account.
Check the recent sign-in activity for your Microsoft account
This is very frustrating. I am getting approx 20 emails a day with a 'did you request a password reset? Here is the code'. The account is secure but it is very annoying. :(
