Hi,
We have a new Exchange 2013 infrastructure up and running and have setup an ARR Proxy Server in a DMZ to allow external users to access the new system for ActiveSync.
I've followed a couple of MS and Exchange blogs to get ARR setup and on initial testing it works great, however we then noticed that external users are able to access OWA via ARR as well but we only want to allow access to ActiveSync.
Can anyone let me know how to change the Rule in ARR to only allow ActiveSync traffic?
Cheers for now
Russell
