Configuring Office Web Apps Server(OWA)with certificate

Office Web Apps Server(OWA) provides updated versions of Word Web App, Excel Web App, PowerPoint Web App, and OneNote Web App. Users can view and edit Office documents in SharePoint libraries by using a supported web browser on computers and on many mobile devices, such as Windows Phones, iPhones, iPads, Windows 8 tablets, and Android devices.

I will be sharing some notes about installation and deployment of OWA based on personal experience and collection from different sources.

To Install OWA  server do the following from PowerShell command:

  • Import-Module Servermanager
  •  Add-WindowsFeature Web-Server, Web-WebServer, Web-Common-Http, Web-Static-Content, Web-App-Dev, Web-Asp-Net, Web-Net-Ext
  •  Add-WindowsFeature Web-ISAPI-Ext, Web-ISAPI-Filter, Web-Includes, Web-Security, Web-Windows-Auth, Web-Filtering, Web-Stat-Compression, Web-Dyn-Compression, Web-Mgmt-Console
  •   Install the OWA server and the latest patches

To configure OWA with SharePoint using https

  • Install OWA certificate  on OWA server open certificate console and start importing the certificate
Note: to get certificate you need authorized certificate generator either your company like Active Directory Certificate Services or 3rd party

The steps to import certificate:

Then open the imported certificate From the Detail tab, click edit properties and add Friendly name: OfficeWebApps.
  • On the OWA Server create OWA farm with association to the certificate.
  Import-Module -Name OfficeWebApps
    New-OfficeWebAppsFarm -InternalUrl "https://officewebapps.x.com" -ExternalUrl "https://officewebapps.x.com" -AllowHttp –EditingEnabled -CertificateName "OfficeWebApps"
  •  ON Central Admin SharePoint server need to create OPI bindings between OWA and SharePoint with new association to https.

So run this command:  New-SPWOPIBinding -ServerName officewebapps.x.com –AllowHTTP
 
Then run this command    Set-SPWOPIZone –zone "internal-https"

Note:
DNS records need to be added for officewebapps URL pointing to OWA server
