Microsoft Teams is Microsoft’s cloud-based collaboration hub, released worldwide on 14 March 2017 as part of the Microsoft 365 suite. It unifies persistent chat, voice and video meetings, file-sharing and third-party apps inside a single workspace, allowing users to switch fluidly between messaging, co-authoring and live calls without leaving the platform. Daily active usage has risen to roughly 280 million in 2025, making Teams the second-most-used meeting product after Zoom, particularly where organisations already subscribe to Microsoft 365.

Typical scenarios include:
- Hybrid and remote workspaces – scheduling and running video, audio or webinar-style meetings; recording and transcribing sessions; issuing polls.
- Front-line and shift-based work – mobile “Walkie Talkie”, shift rostering and approvals via Teams on iOS / Android.
- Project-centric collaboration – dedicated channels with tabs for Planner, Power BI and SharePoint dashboards.
- Cross-organisation events – external webinars with up to 1,000 interactive attendees (20,000 view-only).
- Emerging AI scenarios – live Copilot summaries, and a forthcoming interpreter mode providing real-time speech-to-speech translation in nine languages
