Before you can configure Lync Server 2013 to use Office Web Apps Server, Office Web Apps Server must be deployed and configured. See the document Guide to Deploying Office Web Apps Server and Office Web Apps for detail information on how to install and configure a single Office Web Apps Server, or for information on how to install and configure an Office Web Apps Server Farm for high availability.

After Office Web Apps Server has been successfully installed and your Web farm correctly configured, you must then configure Lync Server to communicate with the new server; this is done by adding the Office Web Apps Server discovery URL to your Lync Server topology. To add Office Web Apps Server to your topology, complete the following steps:

  1. Click Start, click All Programs, click Microsoft Lync Server 2013, and then click Lync Server Topology Builder.

  2. In the Topology Builder dialog box, select Download Topology from existing deployment and then click OK.

  3. In the Save Topology As dialog box, type a name for your topology document (for example, PreWebAppsServerTopology) in the File name box and then click Save. This topology can later be retrieved and republished if you encounter problems with your new topology.

  4. In Topology Builder, expand Lync Server 2013, expand the name of your site, expand Enterprise Edition Front End pools, right-click the name of one of your pools, and then click Edit Properties.

  5. In the Edit Properties dialog box, on the General tab, find the heading Associate Office Web Apps Server and then click New (or select an existing Office Web Apps Server from the drop-down list).

  6. In the Define New Office Web Apps Server dialog box, type the fully qualified domain name (FQDN) of your Office Web Apps Server computer in the Office Web Apps Server FQDN box; when you do this, your Office Web Apps Server discovery URL should automatically be entered into the Office Web Apps Server discovery URL box.

    If the Office Web Apps Server is installed on-premises and in the same network zone as Lync Server 2013 then the option Office Web Apps Server is deployed in an external network (that is, perimeter/Internet) should not be selected.

    If the Office Web Apps Server is deployed outside your internal firewall, then select the option Office Web Apps Server is deployed in an external network (that is, perimeter/Internet).

  7. In the Define New Office Web Apps Server dialog box, click OK, and then click OK in the Edit Properties dialog box. The Office Web Apps discovery URL will then be listed as one of the pool's Associations.

You will have to repeat this process for each pool that needs to be associated with your Office Web Apps Server.

After you have added the discovery URL to the topology you must then publish this updated topology. To do that in Topology Builder:

  1. Click Action and then click Publish Topology.

  2. In the Publish Topology wizard, on the Publish the Topology page, click Next.

  3. On the Publishing wizard complete page, click Finish.

  4. Close Topology Builder.
