Cannot Find Thumbprint by Certificatename

Hi Community user,

This is happening with new environments deployed after mid November. There was a change where a required certificate for communication with Entra ID (formerly known as Active Directory), You would need to install this manually on cloud hosted environments: Secure one-box development environments - Finance & Operations | Dynamics 365 | Microsoft Learn

Hi,
As Andre said, the certificates in the Microsoft Entra tenant are no longer installed in the new one-box development environment. This change affects external integrations (including imported users). To re-enable this feature, new application and tenant certificates need to be set up.
Best Regards,
Hana

Hi thank you so much Hana and Andre, I've followed the link you've mentioned by trying to import/generate certificate in the azure key vault. And uploaded it to the app registration's certificate and installed it inside the VM and modified the web.config file and also added the API permission for the application in azure but now I'm facing this issue " Keyset does not exist " can you please guide me what I've missed?

Verify that the certificate has not been revoked. Revoked certificates will not be trusted by the system.
