I've been playing around with Microsoft Graph in order to be able to send an email from within the Graph Explorer.
This was not possible, because my admin user with which I was logged in did not have Mail.Send permissions, so I clicked "Consent". The tests failed, so I wanted to revoke the Mail.Send permission, which I could only do by consenting to the DelegatedPermissionGrant.ReadWrite.All and Directory.ReadWrite.All permissions. Which I did.
After I revoked my Mail.Send permission, I wanted to revoke the other two, but as soon as I revoked one, I could no longer revoke the other - A needs B to be able to revoke A, and vice versa...
How can I revoke both these permissions from my admin account, and restore the original situation?
