Microsoft 365 features that help users manage their subscriptions, account settings, and billing information.
Hi Melinda,
Since the account is still active and shows it is managed by your brother, I would suggest first identifying the tenant associated with your sign-in address.
You may wish to try the following:
1/ Sign in to Account page > My account > Organizations and check the organization name is displayed.
2/ Go to https://entra.microsoft.com to see the tenant name and Tenant ID.
Once you have that information, ask your brother to sign in to the Microsoft 365 Admin Center or Microsoft Entra Admin Center for the tenant that matches the organization name or Tenant ID you found. He can then search for your account there and, if needed, assign the appropriate administrative role or perform the required HIPAA/compliance-related configuration on your behalf.
