The HTTP Proxy supports the option of working with Outlook Web Access (OWA) as a backend web server. For this option, the HTTP Proxy accepts HTTP/S requests from the Internet and forwards them to the OWA server. Depending on your requirements, the HTTP Proxy provides different options of communicating independently with the OWA server via HTTP or HTTPS in both directions. Therefore, when answering requests with pages that include dynamic links, special requirements must be met for the configuration to provide seamless communication using either HTTP or HTTPS between the HTTP Proxy and the OWA server.
Before You Begin
Configure the HTTP Proxy server to operate in reverse mode.
For more information, see How to Set Up a Reverse Proxy.
Configure the HTTP Proxy to Communicate with the OWA Server
Setting up the HTTP Proxy to work with the OWA server requires you to configure special settings. Since settings on the OWA server depend heavily on special release versions from Microsoft, it is recommended to consult the manuals from Microsoft to correctly set up OWA on the server side.
- Go to CONFIGURATION > Configuration Tree > Box > Virtual Servers > your virtual server > Assigned Services > HTTP Proxy > HTTP Proxy Settings .
- In the left menu, select Reverse Proxy Settings.
- Click Lock.
- Specify your Reverse Proxy Settings. For more information on these settings, see the following Reverse Proxy Settings section.
- Click Send Changes and Activate.
