I have a customer who has EV 11 and Exchange 2013.
I have deployed office mail app and it is available and working from inside the local network.
Is there any special configuration of the perimeter firewall that is required to get Office Mail App to work from the Internet.
It seems to me that it should technically work
In past deployments I would follow the instructions for "Configuring OWA access to Enterprise Vault" and "Using firewall software for external access to OWA and Outlook" from the Setting_up_Exchange_Server_Archiving guide for configuring OWA and the perimeter firewall. The documentation is not explicit for what happens when you have EV 11 and Exchange 2013 and need to configure Office Mail App in OWA.
have you seen these specific to 2013 and Office Mail App?
