I wanted to setup Email for the type Current User. I created an app in Azure, got everything OK (I hope), but when running the set up email wizard, I used the wrong App ID. However, it went through with the wizard, but on logging on, it ofcourse showed a message that the application with identifier "xxxx" was not found in the tenant.
No big thing, you would say: Just remove the app registration, and start over. But that's when it fails. I cannot find the app registration anywhere, I don't know how and where to remove it. I can remove the email type current user, but it does not remove the app registration itself.
How can I remove or change the app registration, so that when running the wizard again, it will not use the already registered app?
