(Updated) Microsoft 365 Copilot: Copilot chat pane and Summary feature in OneNote Mobile (iPhone)

🚨 The Signal: Copilot's AI summary and chat features are coming to OneNote Mobile on iPhone for licensed users. This expands AI access to sensitive notes, increasing data exposure risk if not governed.

The Impact

Users with Copilot licenses on iPhone are affected, increasing the risk of sensitive information exposure via AI summarisation and chat.

• Copilot-licensed users: Risk of sensitive data exposure through AI summarisation.
• Security teams: Need to review and enforce data handling policies for AI interactions.
• Compliance officers: Potential for non-compliance if sensitive data is processed by AI without proper controls.

The Action

1. Review existing Microsoft 365 Copilot data governance policies for OneNote content.
2. Educate users on appropriate data types for AI summarisation and chat in OneNote Mobile.
3. Monitor Copilot usage logs for unusual activity or sensitive data processing.
