Hello Igor Vilghelm,
If you’re seeing an “Azure sign-in failed” error with a message that your tenant has been blocked, it means your organization’s Azure account has run into a serious issue—usually related to billing, compliance, or a security problem.
Here’s what you can do:
Check Email for Details: Microsoft should have sent an email to the tenant admin explaining why access was blocked. Look in your inbox (and spam/junk folder) for any recent messages from Microsoft Azure.
Contact the Admin: If you’re not the main admin, reach out to your organization’s Azure or IT admin. Only the person listed as the global administrator in Azure Active Directory can resolve this.
Resolve the Cause: The most common reasons for a block are unpaid bills, security violations, or policy issues. If it’s a billing problem, update your payment information or settle outstanding invoices in the Azure Portal.
Open a Microsoft Support Ticket: If you’re unsure why you’re blocked or can’t solve it from your side, go to the Azure Portal (using another tenant or a different admin account) and open a support ticket. Microsoft Support can help you understand the reason and guide you through the steps to restore access.
Stay patient—once the issue is identified and resolved, tenants are typically unblocked within a few hours to a couple of days. If your services are business-critical, mention that when contacting support for a faster response.
Best Regards,
Jerald Felix
