Office in Copilot begins rolling out to Frontier customers

Microsoft Copilot Blog Β· 9 Oct 2026

πŸ€– Word, Excel and PowerPoint are moving directly into the Copilot app for Frontier customers using Chat and Cowork.

πŸ’‘ Users can generate a file, edit it alongside the conversation, and collaborate through sharing, comments and coauthoring without creating disconnected drafts.

πŸ” Library brings recent files together, while files retain formatting, permissions and version history as work continues across Copilot and Office.

πŸ€– For Modern Work partners, this changes how a Copilot pilot can demonstrate the complete journey from an initial prompt to a finished team deliverable.

⏳ Availability is the important distinction: the announcement describes a Frontier rollout, not general availability for every customer.
