I am running a POST request to create a OnlineMeeting in with the URL
https://graph.microsoft.com/v1.0/users/{{UserId}}/onlineMeetings
I have the OnlineMeetings.ReadWrite.All Application Permissions
I am able to get the user Id, and the bearer token form Authentication, but when I run the online meeting POST |

{
  "startDateTime":"2019-07-12T14:30:34.2444915-07:00",
  "endDateTime":"2019-07-12T15:00:34.2464912-07:00",
  "subject":"User Token Meeting"
}

As a test it only receive:

{"error":
	{"code":"General","message":"No application access policy found for this app.","innerError":
		{"request-id":"123","date":"2023-10-11T17:18:53","client-request-id":"123"}
	}
}

Hi @tyler cushing

As the error message indicates, the calling application has not created an application access policy.

According to the documentation: To use application permission for this API, tenant administrators must create an application access policy and grant it to a user to authorize the app configured in the policy to create online meetings on behalf of that user (with user ID specified in the request path).

Therefore, before you use daemon creation to create online meetings for other users, you must create an application access policy for the application.

So my use case needs to grant a group of users access to this, would that command to be run for each one? Or does it apply to the app itself allowing access to create meetings on behalf of users?

Hi @tyler cushing

No, you cannot grant application access policy to a group of users, you can only grant it to a single user or to the entire tenant.

Application access policies do not only apply to the application itself. When an application creates an online meeting on behalf of another user, the application access policy must be granted to the target user, otherwise the application will be blocked from creating online meetings on behalf of the user.
