Office Online Server (OOS) is the latest version of what was called Office Web Apps Server, and it is supported for Skype for Business Server 2015.

Customers with a Volume Licensing account can download OOS from the Volume License Servicing Center at no cost and will have view-only functionality, which includes PowerPoint sharing in Skype for Business. Customers that require document creation, edit and save functionality in OOS will need to have an on-premises Office suite license with Software Assurance or an Office 365 ProPlus subscription.

Hardware Requirements

Hardware requirements are still a little vague from Microsoft at this stage. Microsoft say “Office Online Server uses the same minimum hardware requirements as SharePoint Server 2016”. This is probably a little over kill if you are only using the role for Skype for Business, however here they are for your reference:

Scenario Processor RAM Hard Disk
