Microsoft Copilot File Summary Update

Message ID: MC1003344

Updated September 16, 2025: We have updated the timeline. Thank you for your patience.

Users will be able to summarize files with Summarize for me using Microsoft Copilot within one-on-one or group Microsoft Teams chats. This feature will work on common file types like Word and PDF initially, and other file formats will be added over time. This summarization respects the file’s security policies, ensuring that only users with access to the file receive a summary, which will carry the same sensitivity label as the original file. A Microsoft 365 Copilot license is required to use this feature.

This message is associated with Microsoft 365 Roadmap ID 418564.
