Is your request related to a problem? Please describe.
A clear and concise description of what the problem is and the results it had on the environment.

Exchange is an application that has historically been granted an excessive amount of permissions at the Active Directory level

The split permissions models can reduce some of these, but its probably worth having some checks built into HealthChecker that scan for excessive permissions assigned to the Exchange related groups (perhaps these were added manually) or still existing even after a switch to a split permissions model

Describe The Request
A clear and concise description of the feature to add to a current tool or a new tool with what we all want to be checking with examples.

the goal of these checks would be to make the risks of these low level permissions visible to Exchange and domain admins in order to better isolate a compromise in Exchange to just that application and not have it immediately become a domain wide compromise to the entire directory
