Historical Growth
Microsoft Teams launched in March 2017 as a Slack competitor, but its user base remained modest until the COVID-19 pandemic. In March 2020, Teams had 44 million DAUs; by April 2020, it surged to 75 million DAUs. MAUs grew from 20 million in 2019 to 115 million by October 2020. Growth continued as remote work became permanent for many organizations, reaching 145 million MAUs in 2021, 270 million in 2022, and stabilizing around 300 million by 2023. The integration of Microsoft Copilot AI features in 2024 gave a slight boost to 310 million, and by 2026, the platform has reached an estimated 320 million MAUs.
What Is Driving the Change?
Key drivers include the permanent shift to hybrid work, integration with Microsoft 365 (Word, Excel, PowerPoint, Outlook), and the addition of AI-powered features like Copilot for meeting summaries and chat assistance. Competitors like Slack and Zoom have seen slower growth as Teams bundles with Office subscriptions. The platform's free tier also attracts smaller businesses and educational institutions.
Methodology
Official MAU figures are reported by Microsoft in quarterly earnings calls and annual reports. Country-level breakdowns are estimated using regional revenue data, user survey panels (e.g., Statista, Gartner), and internet penetration rates. The 2026 figure is an estimate based on Q1 2026 reported DAUs of 145 million and typical MAU/DAU ratios of ~2.2. All figures should be considered approximate and may be revised.
