What changed since this version
Updated August 7, 2026: We have updated the timeline. Thank you for your patience.
Introduction
We're introducing User Initiated Insights in Copilot for classic Outlook for Windows, enabling users to manually select text within an email and prompt Copilot to provide contextual insights. This enhancement gives users greater control over when and how Copilot assists them, improving productivity, clarity, and decision-making directly within their workflow.

When this will happen:
- Public Preview (Worldwide): We began rolling out in early May 2026 and expect to complete by late May 2026.
- General Availability (Worldwide): We will begin rolling out in early
JuneSeptember 2026 (previously early June) and expect to complete by end of September 2026 (previously lateJune 2026June).
How this affects your organization:
