The error message you are encountering, AADSTS5000225: This tenant has been blocked due to inactivity, indicates that your Azure tenant has been made inaccessible due to a lack of activity. This is a measure to help reduce unnecessary costs for configured tenants that are no longer in use.
To resolve this issue, you can take the following steps:
- If you are the tenant administrator, you can request to reactivate your tenant within 20 days of it entering an inactive state. You can reach out to Microsoft support for assistance.
- If you do not plan to reactivate the tenant, be aware that it will be deleted after 20 days and cannot be recovered.
- If you are an application owner or developer, minimize authentication requests to the deactivated tenant until it is reactivated.
Make sure to follow the appropriate steps based on your role and intentions regarding the tenant.
