Updated January 26, 2026: We have updated the timeline. Thank you for your patience.

[Introduction:]

Microsoft is enhancing Copilot (Microsoft 365) with Context IQ (CIQ), a set of AI capabilities that allows users to search for, select, and insert relevant enterprise or personal data directly into their prompts or conversations. When writing Copilot prompts in the chat box, users will be able to use Context IQ to search for and select Teams channels. This helps ground prompts in contextually relevant data, improving the accuracy and usefulness of Copilot responses.
