# Configuring Office Web App Server for SharePoint 2013

We have a requirement to install and configure Office Web App Server for SharePoint 2013. Our Production environment is already has Office Web App Server 2013 integrated with Lync Server 2013 to use PowerPoint presentations in Lync Online Meetings. Now we had a requirement to add SharePoint Server 2013 to use browser based file viewing feature. My question how can i integrate SharePoint Server 2013 on the same OWA Server if its possible or do i need another OWA server for SharePoint 2013.

You can use the same WAC server/farm for your SharePoint farm that you currently use with Lync. Simply run New-SPWOPIBinding -ServerName wac.example.com to hook up SharePoint to WAC.
• New-SPWOPIBinding uses whatever certificate you've set that shows on the WAC configuration in Get-OfficeWebAppsFarm. The certificate assigned to the WAC farm configuration must be valid for your URLs configured for the WAC farm. – Trevor Seward Aug 29 '17 at 14:55
