Microsoft Teams: Open Teams' apps in new window

🚨 The Signal: Microsoft Teams now allows users to open chat, calls, and other apps in separate windows. This change enhances multitasking but could increase data visibility across multiple screens, potentially impacting data loss prevention (DLP) and information protection policies.

The Impact

End-users are affected by new multitasking capabilities, with a low security risk related to increased data visibility.

• End-users: Can now view sensitive information across multiple windows, increasing accidental exposure risk.
• Security Teams: May need to review existing DLP policies for multi-window scenarios.
• Compliance Teams: Potential for minor challenges in demonstrating full control over data display.

The Action

1. Review existing Microsoft Purview Data Loss Prevention (DLP) policies for Microsoft Teams to ensure coverage for multi-window scenarios.
2. Communicate best practices to end-users regarding handling sensitive information across multiple screens.
3. Consider implementing or refining Conditional Access policies for Teams to restrict access based on device compliance or network location.
