Hi

I've lost my phone. On the phone was the authenticator app installed with the relevant registered o365 account. I'ts an organisational account.

I'm the admin. But as I wrote, I can't change anything due to lost access.

Can you please help me with this issue?

<removed PII>

many thanks in advanced.

    Hello,

    If there's no other admin user in your tenant that can reset MFA for you, you need to contact Microsoft support.

    Find the phone number here for your country: https://support.microsoft.com/en-us/topic/customer-service-phone-numbers-c0389ade-5640-e588-8b0e-28de8afeb3f2

    Important Tip: When using the automated system, clearly say “Commercial Account and Billing Support”. This is the key phrase that routes your call to a live agent.
