Copilot Studio: SharePoint knowledge source not auto-refreshing with file updates

(0) ShareShare

Posted on by vasu24
Copilot Studio – Knowledge Source Not Refreshing or Allowing Manual Refresh the chatbot giving replies from the file I saved in previous response
 
Description-
  • I have a Copilot Studio agent that uses SharePoint documents as a knowledge source.
  • I am updating the files of knowledge source in backend on each time I make an input search chat in the bot
  • When I update the SharePoint files, the Copilot continues to answer from an old version of the content that is of the previous chat I made with the copilot bot
  • On the Agents → Knowledge page I can see the connected SharePoint files, but there is no automatic or as an input “Refresh,” “Sync,” or “Remove” option for any of them.
  • Only after manually refreshing the Knowledge source I am able to get the latest content
Please I request the community to respond on the same.
 
Regards.

    Hi 

    What you’re seeing is expected right now — Copilot Studio doesn’t auto-refresh SharePoint knowledge sources when the underlying files are updated. The agent keeps serving from the indexed copy until you manually refresh the knowledge source from the portal. Unfortunately, there’s no “live sync” option available yet, so the latest file updates won’t be reflected immediately in chat responses. A good workaround is to plan periodic manual refreshes or re-upload if the content changes often.

    Currently, it's not possible to automatically refresh the SharePoint/OneDrive knowledge source in Copilot Studio when changes are made.
    It is also documented here: Add unstructured data as a knowledge source - Microsoft Copilot Studio | Microsoft Learn

    I recommend to create a Power Automate flow that notifies someone when changes are made. That way, they can manually refresh the knowledge source in Copilot Studio to keep the chatbot up to date.
     
    Let me know if you need help with that.
