Microsoft reported rising adoption of its Copilot AI assistant across enterprise users, with new data shared during its latest earnings update. The company linked the growth to broader demand for AI tools within workplace software such as Word, Excel, and Outlook.
Microsoft CEO Satya Nadella said the company reached 20 million paid Copilot seats within Microsoft 365. This marked an increase of five million seats in a single quarter. The update came as part of the company’s financial results, where it also reported steady demand for cloud and AI services.
He noted that large-scale deployments increased during the period. The number of organizations using more than 50,000 Copilot seats rose fourfold. Companies including Bayer, Johnson & Johnson, Mercedes-Benz, and Roche each surpassed 90,000 seats. Nadella also referred to a major agreement with Accenture, which involved more than 740,000 seats.
Nadella described the Accenture deal as “our largest Copilot win to date.” He added that enterprise demand continued to grow across industries. The figures show that adoption is expanding beyond early-stage deployments into broader organizational use.
Microsoft also shared data on user activity within Copilot. Nadella said usage increased alongside adoption. He stated, “Copilot queries per user were up nearly 20% quarter over quarter.” He added, “Weekly engagement is now at the same level as Outlook.”
The company explained that this pattern reflects frequent interaction with the tool. Users now access Copilot as part of daily workflows, similar to email usage. This shift points to deeper integration within routine tasks across Microsoft 365 applications.
Nadella addressed concerns about low usage in earlier reports. He stated, “This is like a daily habit of intense usage.” The company linked this trend to continuous updates and expanded features within the platform. As a result, user engagement continues to rise alongside deployment numbers.
Microsoft attributed part of the growth to new features, including agent mode. This function allows Copilot to complete multi-step tasks directly inside applications. It now operates as the default experience across Word, Excel, and PowerPoint.
Nadella said, “Agent mode is now the default experience across Copilot, Word, Excel, and PowerPoint.” He added, “You now have a new way to delegate and complete work using Copilot.” The feature enables users to automate workflows within documents without switching tools.
The company also confirmed that Copilot supports multiple AI models. Nadella said, “You now have access in chat to multiple models by default.” He explained that the system uses intelligent routing to select the best model for each task. He added, “You can use multiple models together to generate optimal responses.”
Microsoft 365 Copilot includes integrations with external AI systems such as Claude from Anthropic. This approach allows the platform to combine capabilities from different models within a single interface. The company stated that these updates aim to improve task execution and response quality.
Microsoft presented the Copilot data alongside its broader earnings results. The company reported continued growth in cloud services, supported by AI-driven demand. The Copilot figures form part of its wider strategy to expand AI integration across enterprise software.
