Microsoft Teams UI design & app screens

A workplace collaboration hub combining chat, video meetings, calling, and file collaboration, deeply tied into the Microsoft 365 ecosystem. It's used across enterprises as a central place for team communication.

The design is a reference for dense communication UX: persistent channels and chats, a meeting stage with grids and screen share, app tabs embedded in channels, and a left navigation rail. It shows how a large-scale enterprise tool organizes many overlapping functions into one workspace.
