I’m trying to access online meeting details and transcript for any user in my organization using the Microsoft Graph API. My goal is to allow a single application to read online meeting data across all users in the company without needing to specify individual users.

What I’ve Tried:

Application Permissions:

• I granted my application the following permissions in Azure AD:

  • OnlineMeetings.Read.All

  • OnlineMeetingTranscript.Read.All

  • Other related permissions like User.Read.All, Group.Read.All.

• I expected that with these permissions, my app could access meeting
  details for any user in the organization.

Issue: When I try to access a meeting or its transcript with the following API call::

https://graph.microsoft.com/v1.0/users/{user-id}/onlineMeetings/{meeting-id}

https://graph.microsoft.com/v1.0/users/{user-id}/onlineMeetings/{meeting-id}/transcripts/{transcript-id}/content

I receive the error:

{
    "error": {
        "code": "General",
        "message": "No application access policy found for this app.",
        "innerError": {
            "request-id": "xxxx-xxxx-xxxx-xxxx",
            "date": "2024-08-13T19:47:25",
            "client-request-id": "xxxx-xxxx-xxxx-xxxx"
        }
    }
}

My Goal:

I want my application to access online meeting details for any user in the organization without having to manually assign an access policy to each user or group. Ideally, I want a solution where my application can read meeting details company-wide.

Questions:

1. Is there a way to bypass the need for an Application Access Policy
   when using OnlineMeetings.Read.All and OnlineMeetingTranscript.Read.All so that my app can access
   meetings across the entire organization?
2. If an access policy is mandatory, is there a more scalable approach
   to apply it company-wide without manually assigning it to every user
   or group?
3. Are there alternative methods or best practices for achieving
   company-wide access to online meetings using Microsoft Graph API?
