Microsoft 365 features that help users manage their subscriptions, account settings, and billing information.
Welcome to the Microsoft Q&A forum.
Thank you for sharing the background and context. From what you described, this appears to be a complex account‑alignment scenario involving multiple Microsoft accounts, subscriptions, and verification paths built up over time. In cases like this, raising a support ticket with Microsoft Support is often a more effective way to review the situation in detail.
A Microsoft support agent can review the specific accounts involved and, where appropriate, initiate a support call or screen‑sharing session to better understand how everything is currently configured and provide more targeted guidance.
As an initial step, you may want to determine which account you can successfully sign in with:
1/ Open a web browser and go to the Microsoft 365 admin center.
2/ Try signing in with the different email addresses you believe may be associated with your business Microsoft services, and note which account allows you to sign in successfully.
Please be aware that this process may take some time, as identifying the correct sign‑in account is often necessary before a support case can be created.
Once you are signed in, you can use that account to raise a support request with Microsoft Support.
For guidance on how to request support, please refer to: Get support - Microsoft 365 admin.
If you would like, you can also let me know which step you are currently stuck on while creating the support ticket or share a screenshot showing the behavior you are encountering (Please ensure that all personal details such as phone numbers, email addresses, or names are removed before posting anything on this public forum). With that information, I may be able to provide more focused guidance on what to try next.
I hope this information is helpful. Thank you for your patience and understanding. If you have additional questions or need further assistance, please feel free to share them in the comments on this post so I can continue to support you.
