Hello @Akhlesh, Verma ,
Thanks for reaching out.
As per the request id and timestamp ("requestId":"f192ac37-8b05-4a81-a582-13f0f5ca3594" & date:"2021-12-23T11:41:23"), I see that the token was still created with the Azure AD Graph audience "https://graph.windows.net/" rather than the Microsoft Graph audience "https://graph.microsoft.com/", which results in the HttpStatusCode:403:Authorization RequestDenied
error.
As a result, I'd like to request that you revisit and decode your code to ensure that the audience (aka resource) is set to Microsoft Graph: https://graph.microsoft.com/. Additionally, you may check the audience by decoding access token from https://jwt.ms.
Based on my research, I believe you should develop an AuthenticationProvider object as explained below articles which authenticate request to Microsoft Graph. See select a Microsoft Graph authentication provider for an example of how to obtain an authentication provider.
