Microsoft reports over 20 million paid enterprise Copilot seats

On Wednesday, Microsoft announced that its enterprise Copilot tool—integrated into Microsoft’s productivity suite—has surpassed over 20 million paid seats. Despite lingering perceptions regarding the tool’s actual usage, the company reported that both its user base and engagement are growing for the assistant, which is integrated into applications like Word, Excel, and Outlook email. During the company’s quarterly earnings call, Microsoft CEO Satya Nadella highlighted that weekly engagement with the artificial intelligence assistant has reached parity with the company’s Outlook email product. Nadella stated, “Copilot queries per user were up nearly 20% quarter-over-quarter. To put this momentum in perspective, weekly engagement is now at the same level as Outlook” to describe the tool’s adoption. He added that this represents a daily habit of intense usage.

Enterprise adoption of the tool is scaling across large organizations. According to Nadella, the number of companies paying for over 50,000 seats has quadrupled. Large enterprise customers deploying the software include:

• Accenture, which signed a deal for over 740,000 seats, representing Microsoft’s largest Copilot win to date.
• Bayer, Johnson & Johnson, Mercedes, and Roche, which have each deployed more than 90,000 seats.

Microsoft is shifting its product strategy toward Agent mode as the default experience. The company made Copilot’s agentic capabilities generally available last week, allowing the tool to take multistep actions directly within documents. As of last week, Agent mode became the default experience across Copilot, Word, Excel, and PowerPoint. Nadella explained that users now have a new way to delegate and complete work using Copilot. Additionally, the assistant is not dependent on a single AI model. Instead, users now have access in chat to multiple models by default, with intelligent auto-routing in agents that provides critique and counsel. This setup allows users to employ multiple models together to generate optimal responses. For instance, Microsoft’s productivity suite supports models from other providers, including Anthropic’s Claude.

Financial analysts reacted positively to the newly disclosed metrics. Keith Weiss, an analyst at Morgan Stanley, remarked during the earnings call on Wednesday that the Microsoft 365 Copilot numbers are super impressive and ahead of most people’s expectations.

Why it matters

Microsoft’s ability to convert enterprise software users into active AI agents is a critical test for the broader B2B AI market, signaling whether generative AI can move from novelty to daily utility.
