Microsoft Teams: Schedule Channel Meetings from Outlook Calendar

🚨 The Signal: Users can now schedule Teams channel meetings directly from Outlook. This change streamlines meeting creation but increases the potential for sensitive discussions to occur in unmanaged channels, impacting data governance and information protection.

The Impact

All users are affected, increasing the risk of sensitive information being shared in inappropriate or unmanaged Teams channels.

• End Users: Increased risk of inadvertently sharing sensitive data in public or broad channels.
• Security Teams: Greater challenge in monitoring and enforcing data loss prevention policies across Teams channels.
• Compliance Teams: Potential for non-compliance with data handling policies if sensitive information is shared in unclassified channels.

The Action

1. Review existing Microsoft Teams data loss prevention (DLP) policies in Microsoft Purview to ensure coverage for channel messages.
2. Communicate best practices to end-users regarding appropriate channel usage for sensitive discussions.
3. Consider implementing sensitivity labels for Teams channels to guide users on data classification.
4. Audit existing Teams channels for sensitive data exposure using Microsoft Purview content search.
