Error----I'm sorry, but there was an error processing your request. Tried below

Save the workbook to OneDrive/SharePoint and turn on AutoSave

  • Copilot in Excel requires the file to be saved to OneDrive or SharePoint.
  • Ensure AutoSave = ON.
  1. Close and reopen Excel
    • Temporary Copilot service issues are often resolved after restarting the application. Microsoft notes that some Copilot service fixes require an application restart to pick up changes.
    • Save the file as**.xlsx**.
    • Copilot may not work with certain unsupported formats.
    • Check if the workbook is checked out
    • If the file is checked out from SharePoint, Copilot can show errors or unsupported file state messages. Check the file back in and reopen it.
  2. Verify internet connectivity and VPN
    • Copilot requires an active connection to Microsoft services. Connection interruptions can cause processing errors.
    Try a simple prompt
    • Example:"Summarize this table" or*"Suggest a formula for this column."*
    • If simple prompts work but complex ones fail, the prompt or workbook context may be causing the issue.
  3. Update Office
  • In Excel, go to File > Account > Update Options > Update Now.
    • Outdated Office builds can cause Copilot issues.

    Good day Snehal, 

    There is currently a known Microsoft Copilot (Microsoft 365) service incident, CP1470554, which may prevent users from accessing Microsoft 365 Copilot or may cause failures when interacting with the service. At this time, no additional troubleshooting is required on your side.  

    User's image

    I recommend that your organization's IT administrator monitor incident CP1470554 in the Microsoft 365 admin center > Service Health for the latest updates, as Microsoft is actively working on a resolution.  

    Note: In case you do not know who is your IT admin, kindly refer to this article: How do I find my Microsoft 365 admin? - Microsoft Support   

    Once the service has been fully restored, please restart the application and test Microsoft 365 Copilot again. 

    Also, as many members of the community may not yet be aware of this incident, I hope you find this information helpful. Sharing or highlighting this response can help bring greater visibility to the issue, making it easier for others who are experiencing similar challenges to find relevant information and support.    

    If you have any questions or need further assistance, please feel free to share them in the comments on this post so I can continue to support you.     

    Thank you for your patience and understanding.
