Microsoft Copilot for Outlook: New Copilot entry point in Classic Outlook

🚨 The Signal: Copilot in Classic Outlook gets a new, more prominent entry point next to the ribbon. This increases user discoverability and interaction with AI-powered content summarization and drafting, potentially exposing more sensitive data to AI processing.

The Impact

Users with Copilot licenses are affected, increasing the risk of sensitive data exposure to AI processing if not properly governed.

• End-users: Increased interaction with AI features, potentially exposing more sensitive data.
• Security Teams: Need to monitor data flows and AI interactions for compliance and data leakage.
• Admins: Review existing Copilot data governance policies for increased usage scenarios.

The Action

1. Review and update Microsoft Purview Data Loss Prevention (DLP) policies to include Copilot interactions and AI-generated content.
2. Educate users on responsible AI usage, data sensitivity, and not inputting highly classified information into Copilot.
3. Monitor Copilot usage reports in the Microsoft 365 admin center for unusual activity or high-risk data interactions.
4. Verify existing Microsoft Entra Conditional Access policies apply to Copilot access and data handling.
