Introduction
We’re enhancing Microsoft 365 Copilot Chat by enabling users to draft, edit, and send Outlook email directly within Copilot Chat. When Microsoft 365 Copilot identifies an email‑writing intent, it will open an embedded Outlook compose form. This improvement reduces context switching and streamlines everyday communication workflows.
When this will happen
General Availability (Worldwide): Rollout will begin in late March 2026 (previously early March) and is expected to complete by late April 2026 (previously early April).

- The feature will be on by default for all eligible users.
