Editor’s note: This article was originally published on October 5, 2023, and updated on October 31, 2023, to reflect the schedule for the update from classic Teams to new Teams.
October 31, 2023: After March 31, 2024, any classic Teams users that haven't updated to new Teams, will be automatically updated to new Teams. Teams is governed by the Modern Lifecycle Policy, with the expectation that users remain on the most up-to-date version of the desktop client. Please refer to the article to learn more about this announcement.
Today, we are excited to announce general availability of the new Microsoft Teams app for Windows and Mac including education customers. We’re also beginning to roll out new Teams to public preview for our Virtual Desktop Infrastructure (VDI) and government cloud customers (GCC, GCC-H, DoD).
Earlier this year, we ushered in a new era of Microsoft Teams with the public preview of the new Teams app. Our goal was to reimagine Teams from the ground up to deliver a faster, simpler, smarter, and more flexible app to help you stay productive and collaborate more effectively. The preview version of new Teams was up to two times faster while using 50% less memory.
We have made notable progress since the launch of new Teams in public preview. New Teams now has full feature parity for almost all features including custom line-of-business apps, third-party apps, breakout rooms, 7x7 video, call queues, PSTN calling, contextual search in chats and channels, cross-post a channel conversation, and more. We have focused on providing high-quality performance and enhancing the basics in areas such as reliability, security, and IT management to make sure that new Teams meets the evolving requirements of your organization.
With the move to general availability, new features and enhancements will be available exclusively on new Teams. New Teams includes support for Multi-tenant organizations (MTO) and multi-tenant, multi-account (MTMA), which enable seamless cross-tenant communication and collaboration beyond organizational boundaries across multiple tenants and accounts.
Upgrading to new Teams is quick and seamless -- no migration is required! Classic Teams users will be automatically upgraded to new Teams in the coming months. To get started on your new Teams journey today, simply flip the toggle in the upper-left corner of the classic Teams app. With just one click, you can join millions of users who are relying on new Teams to stay connected with colleagues, partners, and customers and achieve more together. This report from GigaOm, an independent analyst firm, will explain why you need to prioritize upgrading to new Teams in your organization.
A faster app optimized for performance on multiple platforms
We built new Teams on the React framework to improve the speed and performance of the app on Windows. Using Edge WebView2 as the host for the new Teams app helped us reduce memory usage and disk space as resources are shared with Edge. Our efforts to update the core technology have been a good move towards providing a more efficient and dependable Teams app. GigaOm reported new Teams to be on average two times faster when loading the app, joining meetings, and switching chats and channels, and consuming up to 50% less memory and disk space than classic Teams.
We’re also seeing significant performance improvements on Mac, including the ability to switch between chats and channels faster, and access relevant information quickly and efficiently with a faster scrolling experience. Teams works natively on Mac, giving Mac users an improved app experience. Mac users will now experience a boost in performance due to more efficient use of device resources and an optimized Teams experience even when using multiple high-resolution monitors during calls or meetings. Some of the new security enhancements on Mac are improved app security through a containerized app model, simplified app updates via Microsoft AutoUpdate, and web security enhancements such as Content Security Policy, Trusted Types and more. Refer to our public preview announcement blog to learn more about the simplified IT management and advanced security measures with new Teams.
With new Teams, we also provide a faster app that has been optimized for more efficient use of system resources in your VDI environment. We have observed improvements in latency for key scenarios such as app launch, switch chat, and join meetings when testing the public preview build that is rolling out this month compared with classic Teams.
A simpler user experience that makes it easier to do more in fewer clicks
New Teams offers a simplified and streamlined user experience, that makes it easier for you to personalize experiences, stay on top of your notifications, and get more done in fewer clicks. We’re excited to roll out enhanced personalization options that allow Windows and Mac users more control over the user interface. New Teams will automatically pick light or dark mode and switch based on your system settings, helping Teams better blend into your workspace. New Teams has improved support for users with color sensitivity, using Windows 11 contrast themes so users can select a color palette that works best for their needs. You can efficiently keep track of your messages and notification activity, with features like "mark all as read” in activity, rolling out now; and "mark all as read” in chats or channels, coming soon to new Teams.
With new Teams, we’re also rolling out improvements to optimize the experience for those who use keyboard shortcuts or screen readers to make sure everyone can use Teams more inclusively. You can use keyboard shortcuts more effectively on new Teams by seamlessly navigating between list items such as activity feed and chat threads, allowing you to get more done with even fewer key presses. We've made some usability improvements for our users who use screen readers. These enhancements make it simpler to avoid repeated information, interpret the common tasks more easily, and arrange channel conversations more effectively, whether they are original posts or responses to posts, and more.
A more flexible app for seamless cross-tenant communication and collaboration
Organizations often find themselves managing multiple tenants whether through mergers and acquisitions, or the need to support global subsidiaries and test environments. The new multi-tenant organizations (MTO) capability in new Teams enables a more seamless experience when collaborating with coworkers in an MTO group and accessing resources in other tenants of the group, regardless of how the identity infrastructure is managed. MTO helps deliver rich collaboration and full-fidelity meeting experience while eliminating silos and bringing users together across tenant boundaries. MTO enables users to connect and collaborate with the right users with improved people search results across multiple tenants.
Features such as multi-tenant and multi-account (MTMA) in new Teams enable you to collaborate more effectively across organizational boundaries, stay signed into multiple accounts simultaneously, and receive real-time notifications no matter which one is currently in use. You can seamlessly engage with users across multiple accounts and organizations without having to drop out of a call or meeting, ensuring no disruption to your workflow.
The cross-cloud authenticated meeting feature in new Teams allows you to seamlessly join a meeting hosted in any Microsoft cloud, whether it is commercial or government cloud, without having to sign out of your account in your home tenant. The host verifies the identities of the participants when the meeting begins. You can be confident that other participants can't access any other information from the host tenant.
A smarter Teams app to level up your productivity
New Teams is the foundation for next-generation AI experiences, such as Microsoft Copilot. Copilot in Teams works alongside you to help you stay on top of your tasks by enabling you to get up to speed on conversations, run more effective meetings, and bring everything together in one place. Copilot in Teams chat helps you get up to speed on conversations by quickly reviewing the main points, action items, and decisions without having to scroll through long threads. You can unlock your meeting productivity by using Copilot in Teams meetings to summarize key discussion points—including who said what and where people are aligned or disagree—and suggest action items, all in real time during a meeting. Using the power of Microsoft Graph, Copilot can find and use info that's buried in documents, presentations, emails, calendar invites, notes, and contacts and bring everything together in your Teams app.
