Microsoft Copilot (Microsoft 365): Initiate Copilot Chat by sharing files to the Microsoft 365 Copilot app on iPhone
When users on iPhone choose the action to share a Word, Excel, or PowerPoint file from a third party app (including Files) and choose Microsoft 365 Copilot as the target app, they will automatically be redirected to a Copilot Chat session in the Microsoft 365 Copilot app with the file summary populated. Users will then have the option to open a preview of the file, or continue their conversation with Copilot Chat.
