Writing Blocks in M365 Copilot

Microsoft 365 Copilot will introduce Writing blocks by mid-September 2026, enabling users to create and refine longer-form content like emails and reports within Copilot. This feature enhances productivity by providing a dedicated editing workspace without leaving Copilot. No action is required, but user communication is recommended.

[What and Why:]

We're introducing Writing blocks in Microsoft 365 Copilot. Writing blocks provide a dedicated editing experience for content such as emails, memos, announcements, reports, and other drafts directly within Copilot.

With Writing blocks, users can create, review, and iteratively refine longer-form content in a structured workspace without leaving the Copilot experience, helping improve productivity and streamline content creation workflows.

[Rollout Schedule:]

• General Availability (Worldwide): We will begin rolling out in mid-September 2026 and expect to complete by late September 2026.

[Impact on Your Organization:]

Who is affected:

• Users with access to Microsoft 365 Copilot.

Platforms/Services:
