If you are not familiar with the Office Online server I recommend to read the Office Online server announcement first. Using Office Online server, you can start using web-based Office components like Word, Excel, Powerpoint in your on-premise environment using a look and feel similar to what you already know from your Office 365 tenant. You can also add support to your Exchange, Skype for Business, Sharepoint and other on-prem server software for enhanced or inline editor or document rendering / preview support.
Microsoft customers with a Volume Licensing account can download OOS from the Volume License Servicing Center for free 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.
