         - install pre-requisite
         - install Microsoft Office Web Application
         - install WAC Language Pack
         - run command New-OfficeWebAppsFarm -InternalURL “https://LyncWAC.YourDomain.Local” -ExternalURL "https://WACsrv.domain.com" –CertificateName “My WAC Server” -EditingEnabled

  • According to the error, Lync Front End server attempt to access Office Web Apps Server discovery URL: https://OfficeWebAppInt.domain.local/hosting/discovery/.

    Please check the Office Web Apps Server discovery URL defined in Lync Topology is  https://lyncwac.yourdomain.local/hosting/discovery

  • Did you change the Office Web Apps Server discovery URL in Lync Topology?

    After you change the URL, you need to publish the topology again. Check if the URL in event log changes.

  • Hi Assraf,

    It looks liek your web app is not correct configured.

    Please check again, that your web app FQDN is correct configured in your Lync topology and that you have configured the web app farm correct with the FQDN of your web Services.

    Here is a detailed Installation instruction.

    Check also your Eventlog for the events 41033, 41032

    If you still have problems

    remove the WAC on the Lync topology, publisch topology, deploy the WAC on the topology, publish topology
