Upgrading to the new Teams is quick and effortless for end-users, with no migration is required. Just turn on the switch in the top-left corner of the classic Teams app to begin the new Teams experience. Chat for today's teams First and foremost, Microsoft Teams provides a modern conversation experience for today's teams. Microsoft Teams supports not only persistent but also threaded chats to keep everyone engaged. Team conversations are, by default, visible to the entire team, but there is of course the ability for private discussions. Skype is deeply integrated, so teams can participate in voice and video conferences. And everyone can add personality to their digital workspace with emojis, stickers, GIFs and custom memes to make it their own. A hub for teamwork Second, Microsoft Teams brings together the full breadth and depth of Office 365 to provide a true hub for teamwork. Word, Excel, PowerPoint, SharePoint, OneNote, Planner, Power BI and Delve are all built into Microsoft Teams so people have all the information and tools they need at their fingertips. Backed by the Microsoft Graph, intelligent services are surfaced throughout the workspace to help with information relevancy, discovery and sharing. Microsoft Teams is also built on Office 365 Groups---our cross-application membership service that makes it easy for people to move naturally from one collaboration tool to another, preserve their sense of context and share with others. Customizable for each team Third, since all teams are unique, we've invested deeply in ways for people to customize their workspace, with rich extensibility and open APIs available at general availability. For example, Tabs provides quick access to frequently used documents and cloud services. Microsoft Teams also shares the same Connector model as Exchange, providing notifications and updates from third-party services like Twitter or GitHub. Further, we are including full support for the Microsoft Bot Framework to bring intelligent first- and third-party services into your team environment. Security teams trust Finally, Microsoft Teams provides the advanced security and compliance capabilities that our Office 365 customers expect. Data is encrypted in transit and at rest. Like all our commercial services, we have a transparent operational model with no standing access to customer data. Microsoft Teams will support key compliance standards including EU Model Clauses, ISO 27001, SOC 2, HIPAA and more. And, as customers would expect, Microsoft Teams is served out of our hyper-scale global network of data centers, automatically provisioned within Office 365 and managed centrally, just as any other Office 365 service.
