Yes, that's exactly what I did in the console. I also created a new package for exchange with the server agents for exchange checked. I built this package, removed Avast from my exchange server and installed the new package.
So Exchange server shield is activated in the console and in the package, but I don't see it anywhere when I open Avast Endpoint Protection Suite on the server. I was hoping to see something in the security / antivirus section along with the other shields... or be able to scan my exchange database manually.
