When using the free Copilot icon in PowerPoint, the message 'I couldn't read your document. Please wait a bit and try again later' is always received. Copilot works in web PowerPoint and all other office desktop apps, but fails consistently in PowerPoint desktop.

I have attempted a quick repair of office, signing out and back in, checking for updates, and ensuring that connected experiences is enabled.

This issue occurs in all PowerPoint files, even brand new ones created in OneDrive.

    Welcome Gotquestions,

    Thank you for the detailed description. Since Copilot works in PowerPoint for the web and in your other desktop Microsoft 365 apps, this appears to be specific to the PowerPoint desktop client rather than the document itself.

    Before suggesting additional troubleshooting, could you please confirm:

    • Are you signed in with a personal Microsoft account or a work/school account?
    • In PowerPoint, go to"File" > "Account" and let us know the Product Information version/build shown there.
    • Does the error appear immediately when opening Copilot, or only after submitting a prompt?
    • Have you tested PowerPoint in Safe Mode (powerpnt`` ``/safe) to check whether an add-in is interfering?

    According to Microsoft documentation, Copilot in PowerPoint depends on the desktop app version, account licensing, network connectivity, and privacy/connected-experiences settings. Since you've already verified updates and connected experiences, the app build and account type would be the next items to check.

    You can find the information at this link:

    I look forward to your update.
