Verify Subscription and User License in Microsoft 365 Admin Center
Check your admin center to ensure the Microsoft 365 subscription is active and properly assigned, as unauthorized third-party purchases can be revoked.
If your subscription was purchased from an unauthorized third-party vendor, Microsoft may flag the domain or account as illegitimate and initiate a deactivation. Verifying your status in the admin center helps identify if the license is still active or has been revoked.
Navigate to the Microsoft 365 Admin Center website and sign in using your administrator credentials.
Go to the 'Billing' section in the left-hand menu, then click on 'Your products' to verify that your Office 365 subscription is listed and shows an 'Active' status.
Navigate to 'Users' > 'Active users', select the affected user's account, and check the 'Licenses and apps' tab to ensure a valid Microsoft 365 license is checked and assigned.
Run the Microsoft Support and Recovery Assistant (SaRA)
Use Microsoft's official diagnostic tool to automatically detect and repair Office activation and account issues.
Contact Official Microsoft Support
