Hi @Richard Rutledge ,
Welcome to our forum!
According to your description, i understand that you want to enable two-step verification for your Microsoft 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 an official article and you can refer to it to try the steps: How to use two-step verification with your Microsoft account.
If you are using a Microsoft 365 account, you can also refer to this: Set up your Microsoft 365 sign-in for multi-factor authentication.
Hope to help you!
