Microsoft Teams: SharePoint app in Teams

🚨 The Signal: SharePoint links in Teams chat will now open directly within the SharePoint app in Teams, rather than a web browser. This streamlines content access but changes the security context for link handling.

The Impact

Users accessing SharePoint links in Teams are affected, with a low security risk related to potential DLP policy bypasses.

• End Users: Experience a new default for opening SharePoint links.
• Security Teams: May need to review DLP policies for in-app link handling.
• Compliance Teams: Potential impact on audit trails for content access.
• IT Admins: No direct administrative action required for this feature.

The Action

1. Review existing Microsoft Purview DLP policies to ensure they adequately cover content accessed within the Teams SharePoint app.
2. Verify that conditional access policies for SharePoint are correctly applied to in-app experiences within Teams.
3. Communicate the change to end-users to manage expectations regarding link behavior.
4. Monitor Microsoft 365 message center for further updates on SharePoint app integration and security controls.
