Artifact Signing (Trusted Signing) – email verification link returns "The request is blocked" (HTTP 403)

I'm completing an Organization Public identity validation for Azure Artifact Signing. I've passed the Verified ID / face check step. When I open the email-verification link, Microsoft's vetting endpoint returns "The request is blocked." / "Service unavailable" (a 403 from https://3pc.microsoft.com/vetting/email_accept).

I've already tried, and it reproduces every time:

• Opening the link in an incognito/InPrivate window
• Signing in with the exact work account matching the Primary Email (MOLECULENT AB tenant)
• Different networks, VPN/proxy disabled
• The link is still within its 7-day validity window

This looks like a server-side 403, not a client/network issue. I have NOT created any duplicate validation requests.

Details:

• Organization: Moleculent AB
• Identity validation ID: c4f3aa80-e94e-405b-958c-2115f3c04831
• Subscription ID: 452e4e0e-9d50-4bc3-bce8-f02ed11480f0
• Tenant ID: 717d35d3-1506-4e44-9222-687fa0bbd669
• Primary email on the request: ******@moleculent.com
• Error timestamp (UTC): 2026-08-11 15:57:38
• Reference ID from the blocked page: 20260811T155738Z-1664885795flp4txhC1STOg8u80000000vx000000000avwd

Could someone from the Trusted Signing / Artifact Signing team reset or unblock the email verification for this identity validation so I can complete it, without creating a duplicate request? Thanks.
