Historical Growth
Microsoft Teams launched in March 2017 as a replacement for Skype for Business. Adoption was modest initially, reaching 20 million MAUs by November 2019. The COVID-19 pandemic triggered explosive growth: from 20 million in early 2020 to 115 million by October 2020, and 250 million by July 2021. Growth then slowed but remained steady as hybrid work became permanent. By 2026, Teams had added about 15–20 million MAUs per year, driven by bundling with Microsoft 365 and new features like Copilot AI integration.
What Is Driving the Change
- Bundling with Microsoft 365: Teams is included in most Microsoft 365 commercial subscriptions, giving it a built-in user base of over 400 million commercial users.
- Hybrid work adoption: Even after the pandemic, remote and hybrid work remains common, sustaining demand for collaboration tools.
- AI integration: Microsoft Copilot for Teams (launched 2024) provides AI meeting summaries, action items, and chat assistance, increasing engagement.
- Enterprise dominance: Over 95% of Fortune 500 companies use Teams, creating a network effect that encourages adoption among partners and suppliers.
- Competitor stagnation: Slack’s growth has slowed, and Zoom has pivoted to broader collaboration, but Teams remains the default for large organizations.
