Office 365 allows you to block all third party apps using Settings -> Org Settings -> User Consent to Apps.
This works great but I want to make an exception for one user.
I was told conditional access could achieve this but I have tried and I am not sure on the exact way to configure this so it achieve EXACLY the same result as the Office 365 setting. Once I get this working I can then easily exclude one user.
I hope someone can help.
