Unable to Login to Azure Portal

The error interaction_required: AADSTS5000225: This tenant has been blocked due to inactivity means the Azure AD/Microsoft Entra tenant that the Azure portal is trying to use for sign-in has been marked inactive and blocked.

Key points and actions:

1. Understand what the error means
   • The tenant associated with the account being used has been inactive long enough that Microsoft has blocked sign-in.
   • As described in the referenced Q&A, this typically happens when a tenant has been inactive for an extended period; after a further grace period it is permanently deleted and cannot be recovered.
2. Check whether the tenant can still be reactivated
   • Tenants can only be reactivated within a limited window after they are blocked. One Q&A notes that administrators can request reactivation within 20 days of the tenant entering an inactive state; after that, the tenant is deleted and cannot be restored.
   • If the tenant has been blocked for less than the allowed period, the tenant administrator must contact Microsoft support to request reactivation. Use the “Contact support” option on the sign-in error page or the global support phone numbers for Azure/Microsoft 365.
3. Try signing in directly with a specific tenant
   • If multiple accounts and tenants are mixed, explicitly target the tenant in the Azure portal URL:
     • https://portal.azure.com/<TenantId>
     • or https://portal.azure.com/<yourTenantName>.onmicrosoft.com
   • This can help ensure the browser is not silently switching to a blocked or wrong tenant.
4. Clean up cached sign-ins and account mix-ups
   • Because multiple Microsoft accounts are being mixed (GitHub-linked, education, personal, etc.), clear cached sessions:
     • Sign out of all Microsoft accounts in the browser.
     • Clear cookies and site data for Microsoft/Azure sites.
     • Then open a private/incognito window and sign in again with the intended work/school or personal account.
   • One user with a similar “cannot access Azure” issue resolved it by signing out of all Microsoft accounts and clearing all site data in the browser before signing in again.
5. If the tenant is already permanently deleted
   • If the tenant has been blocked for longer than the allowed reactivation period, it is permanently deleted and cannot be recovered.
   • In that case, create or use a different active tenant:
     • Sign in to the Microsoft Entra admin center (entra.microsoft.com) with an account that can still authenticate.
     • Go to Entra ID → Overview → Manage tenants and create a new tenant.
     • Then access the Azure portal using the new tenant domain, for example: https://portal.azure.com/<newTenantName>.onmicrosoft.com.
   • From the new tenant, subscriptions and resources would need to be recreated, as the old tenant cannot be restored.
6. If still blocked and within the reactivation window
   • Ensure the global administrator of the blocked tenant contacts Microsoft support (for example, via the phone numbers listed for Unified Support or via a support request if any subscription is still accessible) and explicitly requests tenant reactivation due to inactivity.
   • Do not open multiple support cases for the same tenant; wait for a decision on the first case.

These steps address both the tenant-blocked error and the account mix-up by forcing a clean sign-in and, if necessary, working with Microsoft to reactivate or replace the inactive tenant.
