Reactivate my azure tenant

The error AADSTS5000225: This tenant has been blocked due to inactivity means the Microsoft Entra ID (Azure AD) tenant is in an inactive, blocked state.

Key points from the tenant lifecycle behavior:

• When a tenant is blocked due to inactivity, sign-ins are intentionally prevented and the error shown is expected.
• Administrators have up to 20 days from when the tenant becomes inactive to request reactivation.
• After 20 days in this inactive state, the tenant is permanently deleted and cannot be recovered.

To attempt reactivation (only possible within the 20‑day window):

1. Have a tenant administrator contact Microsoft using the global support phone numbers listed at global support phone numbers.
2. Do not open multiple support requests for the same issue; wait for the decision on the existing case.

If the tenant has been inactive and blocked for more than 20 days:

• The tenant is deleted and cannot be reactivated.
• A new tenant must be created if Azure services are still required.

If the issue is with an Azure subscription that was blocked or deleted due to inactivity (separate from the Entra tenant itself):

• If the subscription was blocked due to inactivity, see the guidance under “What happens if my subscription is blocked?” in the subscription-disabled article.
• If the subscription was deleted due to inactivity, it cannot be reactivated and a new subscription must be created.

For additional help with a disabled subscription (if applicable):

• After reactivation of a disabled subscription, most resources resume automatically, but it is recommended to verify and restart services if needed.
• If there are delays beyond 30 minutes after subscription reactivation, contact Azure Billing Support via the support request link in the subscription-disabled guidance.
