Artifact Signing organization validation (Poland): verification link signs in to the Microsoft Accounts tenant and shows You need permission

Hello Artifact Signing team,

Our Public organization identity validation (sole proprietorship in Poland, Artifact Signing account in Poland Central, Basic SKU) was created on 2026-11-10 and is now in Action Required. The verification link from the email, and the same link from the portal, opens credentials.microsoft.com and ends on /verify/noPermission with: 'You need permission. You are currently logged in as (our primary email) on Entra Azure tenant Microsoft Accounts. To access this page, you must be logged in as an authorized user of the Entra Azure tenant which was used for the enrollment application or change.'

• The Azure subscription and its Entra directory were created with a personal Microsoft account whose address is exactly the primary email of the request. In the directory this account is a guest (#EXT#) with Owner on the subscription and Artifact Signing Identity Verifier on the Artifact Signing account.
• Same result on a PC already signed in to the Azure portal in the correct directory, and on a phone.
• We have not deleted or recreated the request.

This looks like the issue in threads 6029233 (resolved by the team on 2026-10-14), 6063977 and 6064503. Could you please check our existing request and let the individual verification open in our directory? We can share the identity validation ID and the tenant ID privately.

Thank you, Marcin Daniun
