Sending Get Request for subscription (https://graph.microsoft.com/v1.0/subscriptions) there are following results:
Requesting with application permissions I only got the subscription which are created by the application.
Requesting with a delegateToken ( where user is an admin) I get all subscription of user and apps listed. (permission subscrptions.read.all must be set)
But accessing an subcriptions (https://graph.microsoft.com/v1.0/subscriptions/{id} for show, update or delete it works only for the the subscriptions created by the the admin user.
if I try to access other subcription with a get Request, I got this:
{
"error": {
"code": "ExtensionError",
"message": "Operation: Read; Exception: [Status Code: Forbidden; Reason: Access is denied. Check credentials and try again.]",
"innerError": {
"date": "2021-09-07T13:01:15",
"request-id": "f7ddf8bd-562d-487b-bde0-d64b25fd78a8",
"client-request-id": "8806f229-e11d-491f-94f5-207bd0f7103a"
}
Is there a way to access (show, update, delete) other subscriptions, which are not created by the user (the user has admin rights)?
is that possible ?
And if so what must done additional? Adding some special roles?
I hope someone can help me.
