Microsoft on Monday released Office 2019, its “perpetual-license” product for both Windows 10 and the Mac platform. However, the Office 2019 product is only available now for Microsoft’s volume licensing customers. “Volume licensing” applies to organizations that license the software for five or more end users. Consumers right now don’t have access to Office 2019, although the product is expected to become available “in the next few weeks,” according to an announcement by Jared Spataro, Microsoft’s corporate vice president for Office and Windows marketing.

Office 2019 consists of the traditional Excel, Outlook, PowerPoint and Word productivity applications. It includes Access, Project, Publisher and Visio applications as well, but only for Windows users. Office 2019 is only supported on Windows 10. It’s not supported on Windows 7 or Windows 8.1.
