Dear E. Lam,
This typically indicates that the domain is either not associated with an active Microsoft 365 tenant or the account being used does not have administrative privileges.
Verify Tenant Activation Please confirm that your organization has an active Microsoft 365 subscription and that the tenant (e.g., thdisplay.onmicrosoft.com) was successfully provisioned. If the tenant was never activated, you may need to reinitiate the setup via the Microsoft 365 portal.
Check Sign-In Credentials Ensure that the sign-in email you're using is linked to a global administrator account. If you're unsure, try signing in at https://portal.office.com using both email formats.
Use Volume Licensing Service Center (VLSC) If your goal is to check volume license status, you may also access the Volume Licensing Service Center using your registered business email (******@thdisplay.com). This platform is separate from Microsoft 365 and may provide the information you need.
Contact Support for Tenant Lookup If you're still unable to access your tenant, we recommend contacting Microsoft Support directly with proof of purchase or agreement number. Our support team can help verify your domain and assist with account recovery.
