Configure Office Web Applications Server

Open PowerShell and run as admin

Run the following commands:

1. Import-Module OfficeWebApps

2. Get-Command “*Office*”

The first command imports the OWA cmdlets, and the second verifies they are available for your use.

Now, we can create the actual OWA server farm:

New-OfficeWebAppsFarm –InternalURL http://yourserver –AllowHttp -EditingEnabled

Let’s break down the New-OfficeWebAppsFarm parameter:

InternalURL : Use the FQDN of the server to run OWA

-AllowHttp : This command tells OWA which protocol to use when communication occurs between the two entities. HTTP can also be used, but it is recommended that it is used for Dev purposes.

-EditingEnabled : Allows documents to be edited using OWA

To verify that the OWA farm was built correctly, run the following command in Internet Explorer or Edge:


Log into your server, and run the following PowerShell command.

New-SPWOPIBinding -ServerName <WacServerName> -AllowHTTP

The –ServerName is the FQDN of the OWA farm server you just created. It should be the same as the –InternalURL you used earlier. Don’t use ‘Http://’ in the server name parameter, just the FQDN of the server.

By default OWA server farm wants to use HTTPS. You can force it to recognize HTTP with the following PowerShell OWA command:

Set-SPWopiZone –zone “internal-http”

Change the AllowOAuthOverHttp setting in SharePoint 2013 to True

To use Office Web Apps with SharePoint 2013 over HTTP in a test environment, set AllowOAuthOverHttp to True. Otherwise Office Web Apps will not work. You can change the current status by running the following example:


$config = (Get-SPSecurityTokenServiceConfig)

$config.AllowOAuthOverHttp = $true


Test whether the installation was successful:



You should receive the following output:
