Microsoft 365 Free Reporting Tool — Public Teams Report

Microsoft Teams environments grow fast—and without clear visibility, public Teams can easily become a governance concern. Since public Teams are discoverable and joinable by users across the organization, administrators need a simple way to track them.

The Microsoft 365 Public Teams Report, available in the M365 Free Reporting Tool, gives admins instant visibility into all public Teams—without digging through admin centers or writing PowerShell scripts.

What Are Public Microsoft Teams?

Public Microsoft Teams are Teams that are visible to everyone in the organization. Any user can discover and join them without approval.

Public Teams are typically used for:

• Organization-wide communication
• Open collaboration spaces
• Knowledge-sharing communities

Because they are open by design, they require regular monitoring to ensure data exposure and governance policies are respected.

How Do Public Microsoft Teams Differ from Private Microsoft Teams?

The key difference lies in access control:

• Public Teams
• Visible to everyone in the tenant
• Users can join freely
• Higher visibility and collaboration reach
• Private Teams
• Visible only to invited members
• Membership is restricted
• Used for sensitive or limited collaboration

From a governance standpoint, public Teams require more oversight due to their open nature.

How to Generate Public Microsoft Teams Report?

Let’s look at the available methods and their limitations.

1. Using Microsoft 365 Admin Center

The Microsoft 365 Admin Center does not provide a dedicated Public Teams report.

❌ Limitations

• No exclusive listing or filtering of Public Teams
• Privacy setting is displayed but not filterable
• No consolidated reporting or export option


Admins must manually inspect each Team to determine its visibility.

2. Using Microsoft Teams Admin Center

The Microsoft Teams Admin Center improves visibility but still lacks reporting flexibility.

❌ Limitations

• No exclusive filter for Public Teams
• Privacy setting is displayed but not filterable
• No consolidated export
• Requires manual review of Teams


This makes it inefficient for tenants with many Teams.

3. Using Graph PowerShell

Graph PowerShell allows admins to programmatically fetch only Public Microsoft Teams.

Reference Script:

This approach typically:

• Retrieves Teams-enabled groups
• Filters Teams based on visibility (Public)
• Formats and exports results

⚠️ Downsides of PowerShell

• Requires Graph and PowerShell knowledge
• Script maintenance and reuse needed
• Manual formatting and CSV export
• Not ideal for quick or frequent reporting

For many admins, this is unnecessary complexity.
