Where Agent history get stored like queries and responses ?

As an end user You can access your previous conversations directly from the agent in SharePoint via the "..." menu each conversation shows a title and timestamp, and you can reopen it to review responses or continue in context. This history is personal and scoped to you only.

It relies on the shared Copilot platform (not stored as a file or list in SharePoint), which governs retention, deletion, and compliance.

For admins and compliance two levels:

To track interactions (who, when, which agent, which files accessed):

• Microsoft Purview Portal > Solutions > Audit filter by workload AIApp and Copilot
• Minimum role required: Audit Reader

To access the actual text of prompts and responses:

• Microsoft Purview Portal > DSPM for AI > Activity Explorer filter by "Copilot Interaction"
• Each record includes: timestamp, user identity, full prompt, agent response, and files/sites accessed

For SharePoint admins The SharePoint Admin Center provides "Agent Access Insights" reports showing which agents access which content and how often. Without a SharePoint Advanced Management license, data is retained for 28 days and data collection must be manually enabled (reports available about 24 hours after enabling).

Hope this helps!
