Microsoft is reimagining the Teams app and has begun a public preview allowing organizations to experience the new Teams client. The new Teams app includes major updates to the user interface to streamline and simplify the experience while the backend of the app has been overhauled making it significantly faster and using less system resources. With the change in the backend of the app and how the app is built, each feature must be updated. Currently the most common features have been finished and thus the reason for the new public preview. However, there are still many features not in the new Teams app. Over the course of 2023, the new Teams app will be finished, and a transition will begin to bring all customers into the new experience.
