Artifact Signing identity validation failed after Verified ID success

Hello,

I am a sole trader registered in France. I created an Azure Artifact Signing Basic account in North Europe.

During identity validation:

• I completed the identity verification process through the provider linked by Microsoft.
• My phone displayed a technical error.
• The Microsoft credentials page on my PC displayed “Verification successful”.
• Artifact Signing subsequently changed the request status to “Failed”, without explaining why.
• Reopening the verification link now says it has already been used.

How can I obtain the failure reason and request a review or retry? Is a French sole trader eligible for organization validation?

I have Basic Azure support. Please advise how to contact the identity validation team without purchasing an additional support plan.

I can provide request identifiers privately through an official support channel.

Thank you.
