Microsoft Copilot (Microsoft 365): Unified Conversations (Chat History) List

🚨 The Signal: Copilot now unifies all chat history into a single list, improving user experience by centralising conversations. This change simplifies access to past interactions, potentially increasing Copilot adoption and data retention within the service.

The Impact

All Copilot users are affected, with a minor increase in data visibility and potential for sensitive information exposure if not properly governed.

• End-users: Easier access to past chats, increasing potential for data exposure.
• Security Teams: Increased visibility of historical data, requiring robust data governance.
• Compliance Teams: More data to manage within Copilot, impacting eDiscovery and retention.
• Admins: No direct administrative action, but awareness of data sprawl is key.

The Action

1. Review existing Microsoft Purview Data Loss Prevention (DLP) policies for Copilot.
2. Verify Microsoft Purview retention labels and policies are applied to Copilot data.
3. Communicate best practices for handling sensitive information within Copilot to end-users.
4. Monitor Copilot usage and data interactions via Microsoft Purview Audit logs.
