New Tenant Creation Blocked - Error Code 715-123280

Hi Microsoft Support / Community,

We are trying to set up a new Microsoft 365 Work Account for our company to enroll in the Microsoft AI Cloud Partner Program and CSP Indirect Reseller program. However, the registration repeatedly gets blocked at the address/billing validation step with Error Code: 715-123280.

To rule out client-side and network issues, we have already performed extensive troubleshooting to no avail:

• Switched between multiple networks and ISPs (Mobile Hotspot / Cellular, Broadband Wi-Fi)
• Configured and tested different DNS servers (Google Public DNS 8.8.8.8, Cloudflare 1.1.1.1)
• Attempted registration across multiple physical devices (Desktop PC, Laptop, Mobile)
• Contacted phone support (AI assistant is not helping at all -_-)

Error Telemetry:

• Error Code: 715-123280
• EventId: 735a96bf-8cfa-4b7a-a8e5-d948b253f7d9
• SID: cec654b0-dbc2-4902-a3e2-1b11c7291d3d
• cV: zkGZWaKa3u0K+7nJrqZSQI.0.9

Could an engineer please review and manually clear this backend risk flag so we can complete our tenant setup?

Thank you.
