We are a small organization. I have recently taken over as manager and find that we have no Office 365 Administrator. Presumably the previous manager had that role. What can we do to create a new Administrator?
If you know the credentials of the Office 365 Administrator, you can use it to create a new Admin or make your account as an Admin. Also, if your account has a capability to raise a support ticket to Microsoft, you can request assistance to them and they will help you with your concern.
