Microsoft announced the addition of Microsoft Loop to Office. Loop consists of three elements: Loop components, Loop pages, and Loop workspaces.

Loop components: An evolution of Fluid components—are atomic units of productivity that help you collaborate and get your work done in the flow of your work—in a chat, email, meeting, document, or Loop page. Loop components can be as simple as lists, tables, notes, tasks, or as sophisticated as a customer sales opportunity from Microsoft Dynamics 365, and because components stay in sync, no matter how many places they live in, you and your team always work with the latest information.

Loop pages are flexible canvases where you can organize your components and pull in other elements like files, links, or data to help teams think, connect, and collaborate. Pages are optimized for thinking together and getting work done. They can start small and continue to grow to match the size of your ideas and projects.

Loop workspaces are shared spaces that allow you and your team to see and group everything important to your project. Workspaces make it easy for you to catch up on what everyone is working on, react to others’ ideas, or track progress toward shared goals. Teams can collaborate synchronously or asynchronously whenever inspiration strikes.
