Excel Gets Copilot AI to Speed Up Work
Microsoft integrates Copilot into Excel for Windows and Mac, enabling users to generate summaries, fill cells, and create tables through natural-language prompts. The Copilot can reference existing cell values and work alongside standard Excel formulas (IF, SWITCH, LAMBDA, WRAPROWS) to streamline data tasks. Access is currently available for Windows version 2509 (Build 19212.20000) or newer and Mac version 16.101 (Build 25081334) or newer; a web rollout via the Frontier program is planned. Microsoft describes Copilot as a core AI-powered tool for data transformation, with demonstrations showing automatic classification of comments and other data. The update is tied to GPT-5 integration across Copilot, 365, and GitHub Copilot, and a new Smart-Modus that can route to the appropriate model. Microsoft emphasizes privacy: Copilot inputs will not be used to train its models. Usage limits include 100 calls per 10 minutes or 300 per hour.

Copilot Cowork: AI Handles Microsoft 365 Tasks
Microsoft is expanding its 365 Copilot with Copilot Cowork, an AI feature that can automatically generate and execute work plans across Outlook, Teams, and Excel. It analyzes data from emails, files, meetings, and documents, creating milestones, tracking progress, and requesting decisions as needed. Copilot Cowork aims to move beyond chat-style support to autonomous task execution, using a system called Work IQ to orchestrate workflows across apps. The solution can prepare briefs, presentations, and analyses for meetings and product launches, and can perform enterprise research and financial analyses. It is currently being tested with select customers, with wider availability planned for the end of March 2026 via the Frontier program. The article also notes Microsoft’s broader use of multi-model AI, including Claude from Anthropic, within Copilot Studio and related tools, all operating under Microsoft 365 security and governance controls.
Microsoft unveils unified Copilot app to challenge Anthropic
Microsoft is updating its Copilot app for corporate workers, combining coding capabilities with agent-building tools in a single application. The move aims to challenge Anthropic's Claude and attract more Office 365 customers to pay for advanced AI features. The new app includes Home, Code, and Autopilot tabs, with usage-based pricing for the Code and Autopilot parts. Less than 7% of the 450 million commercial Office 365 seats currently have AI licenses, indicating slow adoption. The updated app allows users to select from various AI models, including OpenAI's and Anthropic's, as well as Microsoft's own cost-efficient offering. The company faces competition from Meta's Muse app and other AI agent tools. Microsoft's stock has underperformed most megacap peers this year.
Microsoft Copilot Agent Mode Automates Outlook Inbox
Microsoft has added an "Agent Mode" to Copilot in Outlook, allowing the AI assistant to perform agentic inbox and calendar management on behalf of users. Announced by CEO Satya Nadella and described on the Outlook blog, the feature is available in Early Access through Microsoft’s Frontier program. Agent Mode can sort and prioritise emails, identify unanswered contacts, draft follow-ups, reschedule meetings to resolve conflicts and create agendas, all driven by natural-language prompts. Users can review the Copilot’s proposed actions, adjust settings or veto tasks. Microsoft positions the change as expanding agentic automation inside the Microsoft 365 ecosystem; the article notes Copilot Cowork and Claude-like agent inspirations as related developments.
