A fully managed end-to-end service for digitally signing code, documents, and applications. (formerly Trusted Signing)
Hi Augusto,
Since the portal does not show why the validation failed, only Microsoft's Artifact Signing validation team can confirm whether the issue relates to personal identity verification or company details.
I recommend requesting a review of the existing validation before submitting another application. As your Basic support plan prevents opening a technical ticket, you can ask a Microsoft Q&A moderator to help route the issue to the appropriate validation team.
Please share your validation ID and subscription details only through a secure Microsoft support channel.
Thank you, and feel free to respond back for more assistance.
