Using Classic Outlook on Windows for personal email, calendar, and contact management
Dear Alan BatesAM
Thank you for choosing the Microsoft Community to ask your questions.
Based on your description, I know your consult. If you need to enable two-factor authentication, you need to contact the administrator of your account and ask the administrator to enable multi-factor authentication for you in the administrator center. This will allow you to use two-factor authentication.
This is the difference between a business account and a personal account. We apologize for the inconvenience caused.
If you have any other confusion, you can give feedback in a timely manner and I will continue to help you.
Thank you for your support and understanding. Have a great day.
Sincerely
Katherine
