I accidentally deleted the admin account on the authenticator application, now I can't log in to the admin email account anymore, what should I do?
Sounds like you'll need an account admin to reset the account so a new QR code can be generated with which you can relink the authentication device to your account.
If you are the admin then you can reach out to 365 global customer service here.
