If powershell passes all prereq does that means the load balancer is okay? or does the powershell check if Load Balancer is in SSL offload mode or not? I am not sure how our F5 is setup. Anyway to test this? Also, without applying EP, does that mean i am vulnerable?

We are running Exchange 2016 with CU22 and had to hold off on CU23 due to potential issues with the .NET upgrade requirement and an old third-party agent. We do rely on Public Folders as well. If I understand correctly, we should not enable Extended Protection until we can apply CU23, but, we should...
