Welcome to the Microsoft Q&A Platform!
Based on the information you described, the error code AADSTS5000225 with the message “This tenant has been blocked due to inactivity” indicates that the Azure Active Directory (AAD) tenant associated with your Hotmail account was automatically blocked due to a period of inactivity.
Microsoft applies tenant lifecycle policies to free accounts and subscriptions. If there is no usage, sign-in activity, or open support requests for 12 months, the tenant is marked as inactive. A notification is typically sent before the tenant is blocked.
Once a tenant is blocked, you can no longer sign in to the Azure portal or access Azure resources. If the tenant remains blocked for more than 20 days, it is permanently deleted and cannot be recovered.
- If your tenant was blocked less than 20 days ago, you can request reactivation by contacting Microsoft Support. Only a tenant administrator can request reactivation. You may use the global Microsoft support phone numbers or submit a support request through the Azure portal (if accessible).
- If the tenant has been blocked for more than 20 days, it has been deleted and cannot be restored. In this case, you will need to create a new Azure account and tenant.
- If you still have free trial credits, you may be prompted to upgrade to a pay-as-you-go subscription. In some cases, this can help restore access if the tenant is still recoverable.
Suggested you next steps:
- Try signing up again at https://signup.azure.com using your Hotmail account. If your tenant is still available, you may be able to upgrade and regain access.
- If you cannot access your tenant, contact Microsoft support as soon as possible to request reactivation.
- If your tenant is deleted, create a new Azure account and subscription.
