Office 365 is a cloud-based subscription service that brings together tools to help people work together. By combining best-in-class apps like Excel and Outlook with powerful cloud services like OneDrive and Microsoft Teams, Office 365 lets anyone create and share anywhere, on any device.
Microsoft Sway comes in two forms. The free version, which is available for anyone with a Microsoft Account (Hotmail, Live, Outlook.com etc), and Office 365 Sway, which is bundled in with Office 365 licenses. It helps you and your colleagues express ideas using an interactive, web-based canvas. It lets you quickly and easily produce great interactive designs including images, text, documents, videos, maps, and more. Sway is great for use across multiple browsers and devices, with responsive layouts that adapt to whatever screen a presentation is being viewed on.
