Microsoft 365 Copilot Search is an AI-powered universal search experience optimized for your organization. It provides a familiar search experience that helps users quickly find relevant results from your organization. It offers a simple user experience that helps you find what you need, when you need it in a fast and secure unified search.
Note
Microsoft 365 Copilot Search becomes available in a Targeted release beginning late June 2025. It will become generally available as a Standard release in Q3 2025. Learn more about Standard and Targeted releases.
Unified search across all applications: Copilot Search delivers comprehensive insights into your organization's data by interpreting content across Microsoft 365 applications and beyond. With over 100 connectors now in the Microsoft Catalog, support for custom connectors, and hundreds of connectors from integrated software vendors (ISVs), Copilot Search is the single place for quick information across all your Microsoft and non-Microsoft data sources. Learn more about the Microsoft 365 Copilot connectors gallery.
What to use when: Because it's integrated with Microsoft 365 Copilot, users can find the results they need with search, then seamlessly transition to chat for deeper exploration or follow-up task completion.
How Copilot Search works with Microsoft 365 Copilot
Copilot Search is integrated into the Microsoft 365 Copilot app as a dedicated Search module. This integration makes Copilot Search:
- Comprehensive: A universal search experience that allows users to search across all their Microsoft 365 and third-party data sources to find what they need quickly
- Fast: Delivers fast responses at scale across your organizational content
- Relevant: Uses semantic understanding for highly contextual and precise results
- Simple: Features an intuitive, modern user experience
- Connected: Copilot answers and summaries link Search to Chat
- Personalized: Tailored to individual users and tenants
- Secure: Offers enterprise-grade security and privacy
This design positions search as the organizing layer for AI, while chat remains the workspace for task execution and deeper interactions. For example, if a user searches for what's the status of the Q2 report, Copilot Search may return a summarized answer and offer to continue the conversation in chat for more nuanced exploration or follow-up actions.
Access and eligibility
Copilot Search is available to users with an eligible Microsoft 365 Copilot license at no additional cost. It can be accessed through the Microsoft 365 Copilot app on desktop, web, and mobile platforms. The app is available to users with Entra accounts (work or school).
No action is required by admins or users to set up Copilot Search. If a user has an eligible Microsoft 365 Copilot license, Copilot Search appears as a tab in the Microsoft 365 Copilot app.
Privacy and security
Microsoft 365 Copilot Search adheres to the same data protection, privacy standards, and security configurations as Microsoft 365 Copilot. Learn more about data, privacy, and security in Microsoft 365 Copilot.
Natural language search
Copilot Search supports natural language queries, allowing users to type questions or requests in everyday language. For example, you can search for, show me emails from John about Q4 forecasting sent last week or where is the spreadsheet that breaks down marketing ROI by region?, and Copilot Search will understand your intent and return relevant results from across Microsoft 365, including emails, files, chats, meetings, and more.
Copilot Search goes beyond keyword matching by using AI to interpret context, relationships, and meaning, helping you find what you need faster and more intuitively. It also supports traditional keyword queries for specific words or short phrases, relying on exact or partial matches. But a natural language query can engage AI to better interpret the context of the query, leading to more relevant results.
Answer types
Copilot Search allows admins to curate answers that provide concise, authoritative results that are especially relevant to your organization. These answers are delivered directly in search results and convey information about your organization's acronyms, bookmarks, and people.
- Acronyms: Define terminology used in the workplace.
- Bookmarks: Promote key resources in your organization.
- People: Surface coworkers' roles and show how they fit into the organization.
