As some of you may know, the Office Online Server is the updated replacement for Office Web Apps Server to enable PowerPoint presentation sharing and I’ve recently had the opportunity to deploy Skype for Business Server 2019 and thought I’d write a quick post demonstrating the deployment process.
The following is the guide I used for the deployment:
Deploy Office Online Server
https://docs.microsoft.com/en-us/officeonlineserver/deploy-office-online-server
One of the common questions I’ve been asked in the past for the Office Web Apps server was where do you actually download it because it was once publicly available but Microsoft changed that and now requires it to be obtain from portals such as the Microsoft Volume Licensing Service Center under, where most people probably would never look, the Office Professional Plus product.
Prerequisites
With the Office Online Server installation package downloaded, begin with installing the server roles and features with the following PowerShell cmdlet:
Add-WindowsFeature Web-Server,Web-Mgmt-Tools,Web-Mgmt-Console,Web-WebServer,Web-Common-Http,Web-Default-Doc,Web-Static-Content,Web-Performance,Web-Stat-Compression,Web-Dyn-Compression,Web-Security,Web-Filtering,Web-Windows-Auth,Web-App-Dev,Web-Net-Ext45,Web-Asp-Net45,Web-ISAPI-Ext,Web-ISAPI-Filter,Web-Includes,NET-Framework-Features,NET-Framework-45-Features,NET-Framework-Core,NET-Framework-45-Core,NET-HTTP-Activation,NET-Non-HTTP-Activ,NET-WCF-HTTP-Activation45,Windows-Identity-Foundation,Server-Media-Foundation
Download the following packages and install it onto the Windows Server 2016 server:
.NET Framework 4.5.2
https://go.microsoft.com/fwlink/p/?LinkId=510096
Windows Server 2016 already has this package so attempting to install it as the deployment guide suggests will indicate it is already installed.
Visual C++ Redistributable Packages for Visual Studio 2013
https://www.microsoft.com/download/details.aspx?id=40784
Visual C++ Redistributable for Visual Studio 2015
https://go.microsoft.com/fwlink/p/?LinkId=620071
This package also appears to already exist on a Windows Server 2016 server so the installation will fail.
Microsoft.IdentityModel.Extention.dll
https://go.microsoft.com/fwlink/p/?LinkId=620072
Installing Office Online Server
Launch the Office Online Server installation by executing setup.exe:
Install the application:
Import Certificate for Office Online Server
Proceed by importing the certificate that will be used for the Office Online Server and make a note of the friendly name as you will need to reference that later:
Create Office Online Server (Office Web Apps) Farm
The command for creating the Office Online Server farm is the same as the one previously used for Office Web Apps. Execute the following cmdlet while customizing the appropriate parameters:
New-OfficeWebAppsFarm -InternalUrl “https://oos.domain.com” -ExternalUrl “https://oos.domain.com” -CertificateName “OOS Certificate Friendly Name“
Note that I prefer to use the same URL for both external and internal URLs.
You should be able to navigate to the following URL and receive a similar output once the cmdlet has successfully completed:
https://oos.domain.com/hosting/discovery
Creating and Assigning Office Web Apps Server in Skype for Business Server 2019
Launch the Skype for Business Server 2019 Topology builder, navigate to Shared Components > Office Web Apps Server then right click and select New Office Web Apps Server…:
Enter the URL into the Office Web Apps Server FQDN and the field for Office Web Apps Server discovery URL will automatically be filled:
You should see the new Office Web Apps Servers object created:
Assign the new Office Web Apps Server object to the Skype for Business server:
Proceed to publish the topology:
You should see the following event logged on the Skype for Business server’s Lync Server logs after a few minutes:
Log Name: Lync Server
