Hi @Faye ,
Welcome to our forum!
Looks like your case is more related to your Outlook.com account, right?
If so, please kindly understand that the Outlook tag here we mainly focus on general issues about Outlook desktop client. Based on my research, i found that: If you are unable to use the account recovery form because you don't recognize the additional account security information, use our Sign-In Helper. More information: Account recovery unsuccessful.
Hope to help you! If the above doesn't help, it's suggested that you could post your case in dedicated forum for Outlook.com for more professional advice.
Thanks for your understanding and support!
