Thank you for reaching out here. I hope you’re doing well.
I’d like to better understand your situation so we can point you in the right direction. To help clarify, could you please share a bit more detail on the following:
- Where exactly are you trying to sign in (for example, Microsoft 365 admin center, Office apps, etc.)?
- What happens when you try to sign in to the administrator account? Are you seeing a specific error message or being blocked at a particular step? If possible, a screenshot of the error (with any personal or sensitive information removed) would be very helpful so we can better understand what’s stopping the sign‑in.
- Are you mainly trying to regain access to the existing admin account, or are you looking to set up a new subscription / tenant so you can create new email addresses from scratch?
Once I have a clearer picture, it will be much easier to guide you on the correct next steps. If you have any updates or additional information you'd like to share, please feel free to let me know.
I look forward to your update and will do my best to help based on the information you can share.
