New Tenant Creation Blocked - Error Code 715-123280

Please note that this forum is a community support space. I don't have access to Microsoft's provisioning systems and cannot review Event IDs, SID values, billing validation records, or clear backend risk flags.

Dear @ardian nugroho,

Thank you for providing the detailed troubleshooting results and telemetry information.

Based on the steps you've already completed, I agree that this does not appear to be a client-side issue. Since the error persists across multiple devices, networks, ISPs, and DNS providers, the failure is more likely occurring during Microsoft's backend tenant provisioning, security validation, or billing/address validation process. Similar reports involving Error 715-123280 have been associated with tenant creation and signup failures that require backend investigation rather than additional browser or network troubleshooting.

Because tenant creation is being blocked, my first recommendation would be to open a support case from another Microsoft 365 tenant, if you or your organization have access to one. You can do this from: Microsoft 365 Admin Center>Support>Help & Support.   

For reference:  Get support | Microsoft Docs    

When creating the case, explain that you are attempting to create a new Microsoft 365 tenant for Microsoft AI Cloud Partner Program and CSP Indirect Reseller onboarding, but the signup process consistently fails with Error 715-123280 during the address/billing validation stage. Include the Error Code, EventId, SID, and cV values in the request.

I would also recommend continuing to pursue the official Microsoft support phone channel, as this is one of the supported escalation paths for onboarding, commerce, and provisioning-related issues: Customer service phone numbers - Microsoft Support 

When you reach the automated system, it may help to describe the issue as:

• The reason for the call must be the term AdminCenter
• The role must be specified as Global Administrator.
• In the description of the request, the term AdminCenter must be mentioned.
• In the course of the telephone dialog, the question about another administrator can be answered with no, then it is forwarded to a support agent, and a service request can be created.

I would also recommend calling during opening hours when possible. From my experience, it can be difficult to reach the right support queue at times, and automated systems don't always behave as expected. If you can't get through on the first try, consider trying again later or at a different time of day.

Unfortunately, the community cannot review the provisioning telemetry or manually clear any backend validation blocks. This issue will require investigation by a Microsoft team with access to the tenant provisioning systems.

I hope Microsoft Support can review the backend validation records and help complete the tenant creation process so that you can proceed with your Microsoft AI Cloud Partner Program and CSP enrollment.

Warm regards,
