copilot file previews

Copilot file previews refers to the Copilot-assisted document preview experience Microsoft documents for its mobile apps, where search results can surface files with preview support. Coverage under this tag centers on how Microsoft 365 Copilot mobile search is described in official support documentation, and how that documented behavior relates to roadmap changes. A recurring theme is the gap between roadmap planning records and shipped or documented functionality, including the cancellation of roadmap item 485731 for Copilot in the mobile search tab. The practical takeaway for Windows and Microsoft 365 users is to treat support documentation, not roadmap forecasts, as the guide to current Copilot file preview behavior.
