 Workplace intelligence plugin that connects AI agents to Microsoft 365 Copilot, providing access to organizational data from Outlook, Teams, SharePoint, OneDrive, and Calendar.
 
+Powered by the [`@microsoft/workiq`](https://github.com/microsoft/work-iq-mcp) MCP server.
+
+> ⚠️ **Public Preview:** Features and APIs may change.

 ## What it does
 
 WorkIQ grounds AI assistance in real workplace context by querying Microsoft 365 data sources. It enables agents to answer questions about:
 
-- **Emails & messages** — Find and summarize email threads and Teams conversations
-- **Meetings** — Retrieve decisions, action items, and context from calendar events
-- **Documents** — Locate specs, design docs, and files across SharePoint and OneDrive
-- **People** — Identify subject-matter experts, project owners, and organizational relationships
-- **Priorities** — Surface what colleagues are focused on, team goals, and project status
+| Data type | Example questions |
+| --- | --- |
+| **Emails** | "What did John say about the proposal?" |
+| **Meetings** | "What's on my calendar tomorrow?" |
+| **Documents** | "Find my recent PowerPoint presentations" |
+| **Teams** | "Summarize today's messages in the Engineering channel" |
+| **People** | "Who is working on Project Alpha?" |
