Azure free trial sign-in failed with AADSTS5000225, but USD 100 was charged after adding credit card

Hello,

I created an Azure free trial account and was asked to enter my credit card information during the sign-up process, so I entered my card details.

After that, I received an email saying:

“Welcome to your Azure free account”

However, when I tried to sign in to Azure, I received the following error:

Sign-in failed Error code: interaction_required Error message: interaction_required: AADSTS5000225: This tenant has been blocked due to inactivity. To learn more about tenant lifecycle policies, see https://aka.ms/TenantLifecycle

Trace ID: e0057144-07d4-4093-b800-582fe39e0100

Correlation ID: 019dd946-128c-7917-96c2-b0fa72a30e64

Timestamp: 2026-04-29 12:45:42Z

Also, USD 100 was charged to the credit card I registered during the Azure free trial sign-up process.

I have a few questions:

1. Why is my newly created Azure free trial tenant blocked due to inactivity?
2. What is the USD 100 charge for?
3. Is this charge only a temporary authorization hold, or is it an actual payment?
4. Since I cannot access the Azure portal due to the tenant error, how can I check the billing details?
5. If this charge was not intended, how can I request cancellation or a refund?

Please help me reactivate the tenant or explain how I can resolve this billing issue.

Thank you.
