Stuck in an authenticator loop

I have a 365 Business account. Haven't logged in for a while due to reasons, i was just starting up as a sole trader. Anyway decided now is the time to resurrect it and get up and running, except Authenticator doesn't work because I changed my phone, and my back up email is out of date, and no longer exists. I have tried the support web chat which wants to send a code to authenticator or my back up email. Just called the help line that referred me to the web chat which doesn't work, I couldn't get past the bot. So I am stuck. Any recovery options does not recognise my log in details, i think this is because its been a while since I logged in (I still pay but ....) but I can't resurrect it because I don't have a way of getting a code due to authenticator/back up email as cited above. I am really at a loss as to what to do. I don't want to abandon it and start again as there are documents in my one drive that I need. Can anyone help please. (I think all that needs to happen is an update to my back up email and then I can get going). I am the sole administrator on my business account.

  • You cannot bypass Microsoft Authenticator or an outdated backup email on a Microsoft 365 Business account by yourself. As the sole administrator, the only way forward is to contact Microsoft support, who will verify your domain ownership and reset your Multi‑Factor Authentication (MFA) so you can register new methods.
