Hi John,
Just to gently clarify before we go any further, this is a user‑to‑user support forum. I don’t have the ability to access or investigate individual accounts, and do not have access to internal systems or the ability to directly take action on Microsoft product features.
According to Microsoft's article on Activate Microsoft perpetual products using the Product Activation Portal, beginning December 3, 2025, the traditional telephone-based product activation automation process was moved from telephone to an online workflow through the Product Activation Portal.
If you have not already done so, you may try the steps mentioned in the AI answer or in this link: Activate Microsoft perpetual products using the Product Activation Portal to activate your Visio 2010 license through the portal.
If the issue persists, you may try contacting Microsoft Support through the Product Activation Portal for further assistance.
I hope everything gets sorted out soon.
