A fully managed end-to-end service for digitally signing code, documents, and applications. (formerly Trusted Signing)
Hello @Antony Newsome,
Based on your description, I understand that you are unable to submit a new organization validation request.
As of April 2, 2025, Microsoft has updated its Trusted Signing public preview program. The service is now limited to new customer subscriptions from organizations based in the United States and Canada with at least three years of verifiable history. As a result, organizations from other countries are currently unable to submit new validation requests for the remainder of the public preview phase, as individual developer onboarding has been paused.
At this time, there is no estimated timeline for when this feature will be available for other countries. I recommend keeping an eye on Microsoft communications for updates on the expansion of the Trusted Signing service to additional regions. You can also post a comment on this post for updates, and I will share any new information with you as soon as it becomes available.

I hope this information is helpful. Please feel free to reach out if you have any further questions.
