We created a Webhook for receiving "Delete" notifications when a user is deleted from Azure AD. But we're not receiving any notifications when we delete a user. In AAD the user is first placed in the recycle bin, but also if we remove the user from the recycle bin, we don't receive any notifications. We've tried our code with receiving emails -> that worked. And with changing a user in AAD -> that also worked. So we changed "updated" to "deleted" and no calls are triggered.
We started with de documentation (https://docs.microsoft.com/en-us/graph/webhooks) and the sample code provided by Microsoft (https://github.com/microsoftgraph/aspnet-webhooks-rest-sample)
We use Permission Scopes: User.Read.All & Directory.Read.All
Graph Webhook subscription: Resource: "users" ChangeType: "deleted"
When we specify "updated" as ChangeType, we received notifications, as expected. But ChangeType "deleted" was not giving any notifications. Is this not supported, or are we missing a permission... I hope someone can help.
