We are trying to exchange the Microsoft teams chat between our internal group from .Net application.

The "Certificate Access Denied" error when using the Microsoft Graph API to access Teams data typically indicates an issue with the certificate or authentication configuration.

Anyone please share your idea to fix this issue.

Thanks for raising this @softsathian

Any chance you can provide more information on how your certificate is stored? Is it in a store that required admin access or do you fetch it from KeyVault? Does this error occur all the time or intermittently?
