Hello @Stephanie Swikehardt
Thanks for your post.
I would like to gather you some guidance on this concern but I need to know few details first...
-Is your business account a Microsoft account o any other?
-Did you log in on a web browser(PC device) or mobile phone?
-when you stated you are the administrator.... Are you an IT admin/Azure Active Directory admin?
-Have you try to use any Trusted Device to log in to your account? >>"A previous device used for log in to your business account"
-Have you ever configured an email account to backup your MS authenticator data before?
-Do you save previously any backup code for this specific account? So, you can bypass the MS authenticator by using it
Looking forward to hear back from you...
