Microsoft has announced four Copilot updates, some already live or in preview, others rolling out soon, that are designed to simplify tasks, improve control, and boost productivity. These enhancements include smarter content referencing, flexible reasoning modes, customizable response scoping, and integrated meeting scheduling. Timelines may change, so keep an eye on official updates.
Copilot Chat Enhancements: Reference Files and Emails Easily
Copilot Chat for users with a Microsoft 365 Copilot license is being enhanced by introducing quick access to emails directly in prompts. By typing “/” in the prompt box, users can search and reference relevant content without manual uploads, improving prompt quality and Copilot responses. Suggested prompts beneath the input box will also include relevant files or emails for faster starts. This capability will surely reduce friction and ensure responses are grounded in the right context (Also now known as ContextIQ).
This update is associated with Microsoft 365 Roadmap IDs 497112 (files) and 500377 (emails). Files are already available, while email access, originally planned for mid-September through late October, is now postponed to early October through late November. I have seen both features in a couple tenants, but not all. So it might take a couple of more days before you see it in your own tenant.

Reasoning Modes in Copilot
As announced earlier, GPT‑5 is now becoming default model, and Microsoft is introducing a new capability that allows users to select how much reasoning Copilot applies.
Users can now choose among three modes: Auto (default), Quick response, and Think deeper. The rollout for this feature began December 4, 2025, and is expected to complete within a week or two.
This update is associated with Microsoft 365 Roadmap ID 532736.
Content Source Selection for Copilot Chat
Microsoft is introducing a new capability that allows users to scope Copilot Chat responses by selecting specific content sources. This enhancement improves relevance and transparency by limiting responses to user‑selected sources, addressing feedback for more customizable AI interactions.
This feature is associated with Microsoft 365 Roadmap ID 496596. Originally planned for late November through mid‑December, rollout is now postponed to mid‑December through late December 2025.
Meeting Scheduling Directly from Copilot Chat
Microsoft is introducing the ability to schedule meetings directly from Copilot Chat, reducing context switching and improving collaboration. Users can find available times, book rooms, draft agendas, and send invites, all without leaving the chat experience. General Availability rollout began in late November 2025 and is expected to complete by late January 2026.
The feature will be on by default once enabled, with no admin configuration required. Existing calendar and meeting policies remain respected.
