CSP - Deployment on Exchange Cluster suggestions

I have been doing the RT*M and see that it is "suggested" that we start with the CORE policy and tailor from there.  I cannot find any White Papers on CSP/Exchange best practice.  Core is applied and prevention is "disabled" on the 9 nodes in the cluster for the time being while I gather logs.  With the generic config described, if I enable as is, will it break Exchange?  Does anyone have documantation that describes a CSP/Exchange deployment?

Suggestions on appropriate tailoring would be appreciated.

Warnings on what to avoid would be VERY welcome.

Thank you.
