    Hi AT-02100329-0 ​​​​​​​,
     
    This is likely because Copilot caches the knowledge or indexes files for faster retrieval.
    • Go to the Knowledge section in Copilot Studio and temporarily remove the SharePoint library or other data sources connected to your bot. After removing, wait for a few minutes and then reconnect the same data source. This should force Copilot to re-fetch and re-index all available documents.
    • After making changes (like deleting files from the knowledge base), make sure to re-publish the bot. Go to the bot settings in Copilot Studio, and ensure that it is published with the latest changes. This may force a re-index of the data.
    Thanks.
