Federated identity management using Active Directory Federation Services
To request reactivation of a Microsoft Entra (Azure AD) tenant that is blocked with error AADSTS5000225, the tenant administrator must contact Microsoft Support directly. Tenants blocked due to inactivity can only be reactivated within 20 days of entering the inactive state; after 20 days they are permanently deleted and cannot be recovered.
Use the global support phone numbers to open a support case and provide the tenant details (including Tenant ID and the error information) so the support team can review and, if eligible, reactivate the tenant. While the case is in progress, do not submit additional assistance requests for the same issue.
If the tenant is not going to be reactivated, it will be deleted automatically after 20 days in the inaccessible state in accordance with Microsoft’s data protection policies.
