deep citations

The deep citations tag covers Microsoft 365 Copilot's planned citation improvements, centered on links that take users directly to the relevant passage in a referenced source instead of only opening a file or source container. The available coverage focuses on Microsoft roadmap item 523223, listed as in development as of July 8, 2026. Preview is planned for August 2026, with general availability targeted for September 2026 across desktop, Mac, and web for worldwide standard multi-tenant customers. The initial preview scope is described as using Word and PowerPoint references, making this tag useful for tracking Copilot citation behavior and its rollout timeline.
