What Is Microsoft 365 Copilot?
Copilot is Microsoft's flagship AI layer across the productivity stack. Unlike a generic chatbot, Copilot is grounded on Microsoft Graph — your tenant's Exchange, OneDrive, SharePoint, Teams, and Viva signals — meaning it can answer questions like "summarize the last 5 emails from Priya about the Q3 launch" using your actual data. Copilot Studio lets IT and business users build custom agents without code and deploy them as Teams apps, SharePoint assistants, or autonomous agents.
Why Enterprises Are Deploying Copilot in 2026
IDC's 2026 Worldwide AI Productivity Tracker estimates 65M paid M365 Copilot seats globally, up from 1.3M at launch in late 2023. Gartner's 2026 Magic Quadrant for Digital Workplace named Microsoft a Leader, calling Copilot the "default productivity AI for Fortune 2000". Microsoft's own Work Trend Index 2026 reported Copilot users save an average of 14 hours per month on document creation, email triage, and meeting prep.
Forrester's 2026 Total Economic Impact study of Copilot found a 112% ROI over 3 years for enterprises with 1,000+ seats.
