I am trying to test Office Web Apps in an Exchange 2013 test environment and therefore have setup my farm for HTTP only. I have set the WAC Discovery End Point on the Exchange server and I can browse to the XML successfully however when I preview files they are still being displayed using Web-Ready Document Viewer. I have checked the Event Log and found event ids 140 and 141.
Event 141 lists the following error - There was a failure connecting to or otherwise retrieving Data from the Wac Discovery Service. We will fall back to stellent. Successfully retrieved configuration data from http://server01/hosting/discovery, but retrieved discovery xml does not contain an external https net zone node.
Do I need to configure HTTPS with a certificate in order to get this working in a test environment or should it work with HTTP?
Thanks
