Office Online Server is the next version of the Office Web Apps, which allows your users to view and edit Microsoft Office documents directly in their browsers. It is also a prerequisite to have the Durable Links feature of SharePoint 2016 on-premises work properly. Just like its 2013 predecessor, Office Online Server 2016 needs to be installed on its own server, and cannot coexist with a SharePoint installation. It can still be used as a standalone installation.
In the present article, I will go over the installation process. The farm I will use is a SharePoint 2016 farm hosted in Azure. It has one SQL Server with the SharePoint 2016 Application Server MinRole installed on, a Web-Front end (MinRole), and a standalone Office Online Server (OOS) node.
In this article, we will be installing Office Online Server on an Azure server named AzureSPOOPS (not an typo, the ‘p’ was there for -on-premises). The server is running Windows Server 2012 R2 and is a brand new Azure Cloud Virtual Machine I just created. If you simply try to run the setupe.exe application from the installation media on a new server, you will get the following error. Please note that this article was written at a time when the Office Online Server had just been made available for 3 days, so installation steps and screens are likely to change once the product its RTM.
As the error message states, we need to first start an enable the Web-Server role on the server in order for the installation to work. This can be done two ways:
1 – Using the Graphical User Interface:
a) Launch Server Manager and click on Manage > Add Roles and Features
b) Click Next on the first screen
c) Keep the default Role-based or feature-based installation option selected, and click Next
d) Keep the option Select a server from the server pool selected, making sure that the local server in selected in the Server Pool list, and click Next
e) On the Select server roles screen, scroll down to the bottom of the list, and check Web Server (IIS). Click Next
f) A prompt will appear, simply click on the Add Features button
g) On the Select features screen, select Ink and Handwriting Services then click on Next
j) On the Confirm installation selections screen, click on the Install button
Let the installation progress finish and close the window.
2) Use PowerShell:
Using PowerShell, the Web-Server role can be enabled by simply calling the following line of code:
Install-WindowsFeature -Name Web-Server,InkAndHandWritingServices -IncludeAllSubFeature
After a minute or two, the role should be activated and the following output should be shown in the PowerShell console:
We are now ready to re-run the setup.exe installation application for the Office Online Server. This time, instead of getting the error message, we should be presented with the License Terms screen (yes, the title says Microsoft Office Online Server 2013, which in theory never existed). Click I accept the terms of this agreement and click on the Continue button.
Keep the default installation path, unless you have a requirement to put the files in a separate location (e.g. different disk drive). Click on the Install Now button.
Wait for the installation progress to finish
The installation progress should take about 5-6 minutes. Once completed, you will be presented with the following screen. Simply click on the Close button.
Creating the Office Online Farm:
After installing the Office Online Server 2016 bits, in order for the product to be usable, we need to configure a new “Farm”. This is achieved with PowerShell, using the following lines of code. Launch a new PowerShell console running as administrator and simply replace the URL with yours:
Import-Module OfficeWebApp New-OfficeWebAppsFarm -InternalUrl "HTTPS Url" -ExternalUrl "HTTPS Url" -SSLOffloaded –EditingEnabled
*Note SSLOffloaded should only be used in dev/test environments. In production you will want to have the communication done over SSL.
When prompted to turn setting EditingEnabled to TRUE, enter Y. Once completed, the following screen will be shown:
At this point, our job is done for the Office Online Server 2016 configuration. You can go ahead and test that the “Farm” was successfully created by trying to access http://<server name>/hosting/discovery using Internet Explorer (or edge if using Windows Server 2016 Preview). If everything worked, you should see the server’s XML WOPI output as shown in the figure below:
Connecting SharePoint 2016:
Now that the Office Online Server 2016 bits have been installed, the next step is to actually tell our SharePoint 2016 farm about the existence of this new server. In order to do this, launch a new SharePoint Management Shell console on one of the SharePoint 2016 server. What we need to do now is declare a new WOPI binding on the SharePoint server to tell it about the existence of the new Office Online Server 2016 farm. This is done by executing the following line of PowerShell:
New-SPWOPIBinding -ServerName <servername> -AllowHTTP
*Note that -AllowHTTP is ok for non-production environments only. In a production environment you’ll want to ensure communication is done over SSL.
If the command worked, you will see a lot of Office specific properties being output on screen
We are now all set!
