A cloud-based identity and access management service for securing user authentication and resource access
The error message you are encountering, AADSTS5000225: This tenant has been blocked due to inactivity, indicates that the tenant has been made inaccessible due to a lack of activity. This is part of Microsoft's tenant lifecycle policies, which aim to reduce unnecessary costs associated with inactive tenants.
If you need to reactivate your tenant, the tenant administrator can reach out to Microsoft support. It's important to do this within 20 days of the tenant entering an inactive state, as tenants that remain inactive for longer than this period will be deleted and cannot be recovered.
If you do not plan to reactivate the tenant, it will be deleted after the 20-day period, and you should review Microsoft's data protection policies for further guidance.
For more information on handling inaccessible tenants, you can refer to the relevant Microsoft documentation.
