Introduction
A few customers have expressed concerns regarding users being able to view a complete list of tenant members when sharing a Plan. In response, we are pleased to announce that Planner will soon support Information Barriers across both the Planner Web and Planner app within Teams. This feature ensures users can only discover others within their assigned group. Please note that Information Barrier functionality will not be available on the Planner mobile app or when accessing Planner via mobile browsers.

Opportunities**

Enhanced Compliance Management
With the introduction of Information Barriers in Microsoft Planner, organizations can better enforce compliance by restricting access to plans and tasks based on user groups. This ensures sensitive information is only accessible to authorized personnel, reducing the risk of data breaches and enhancing overall data governance.
   - next-steps: Review and update existing Information Barrier policies to align with the new Planner functionality, ensuring that they are configured correctly for all relevant user groups.

Improved User Experience
By limiting visibility of plans to authorized users only, the user experience is enhanced as team members will only see relevant tasks and plans, minimizing confusion and streamlining collaboration within their designated groups.
   - next-steps: Conduct user training sessions to familiarize team members with the new functionality and the benefits of working within their authorized groups, emphasizing the importance of data security.

Streamlined IT Administration
The automatic enforcement of Information Barriers reduces the administrative burden on IT teams by eliminating the need for manual oversight of plan sharing and access control, allowing them to focus on more strategic initiatives.
   - next-steps: Implement a monitoring process to review the effectiveness of Information Barriers and gather feedback from users to continuously improve IT service delivery.
