Microsoft Reports Over 20 Million Paid Copilot Users with Growing Engagement

Apr 30, 2026

Microsoft announces that Microsoft 365 Copilot has reached 20 million paid enterprise seats as of January 2025, with engagement metrics showing nearly 20% quarter-over-quarter growth in queries per user and weekly usage now matching Outlook levels. The company quadrupled the number of organizations paying for over 50,000 seats, with major deployments including Bayer, Johnson & Johnson, Mercedes, and Roche each exceeding 90,000 seats, while Accenture signed Microsoft's largest deal for over 740,000 seats. Morgan Stanley analyst Keith Weiss called the numbers super impressive and ahead of expectations. Microsoft recently made agent mode the default experience across Word, Excel, and PowerPoint, enabling multi-step actions in documents, while adding multi-model support including Anthropic's Claude to reduce dependency on OpenAI.
