Microsoft 365 Free Reporting Tool — Private Teams Report

Private Microsoft Teams are essential for confidential collaboration—but they can also become blind spots if admins don’t have clear visibility into where restricted collaboration exists.

Unfortunately, Microsoft’s native admin tools don’t offer an easy way to list only Private Teams. This often forces administrators into manual checks or PowerShell scripts just to answer a simple question: Which Teams in my tenant are private?

The Microsoft 365 Private Teams Report, available in the M365 Free Reporting Tool, solves this problem by giving admins instant, exclusive visibility into Private Teams—without scripting or manual digging.

What Are Private Microsoft Teams?

Private Microsoft Teams are Teams where membership is restricted and controlled by Team owners.

Key characteristics:

• Only invited users can see and join the Team
• Team content is hidden from non-members
• Used for sensitive projects, departments, or leadership collaboration

Because access is tightly controlled, Private Teams are often subject to stricter governance and audit requirements.

How Do Private Microsoft Teams Differ from Public Microsoft Teams?

The difference lies in visibility and access control:

• Private Teams
• Not visible to non-members
• Membership by invitation only
• Used for confidential collaboration
• Public Teams
• Discoverable by everyone in the tenant
• Users can join freely
• Used for open collaboration

From an admin perspective, Private Teams require periodic review to ensure access remains appropriate.

How to Generate Private Microsoft Teams Report?

Let’s examine the available options—and why they fall short.

1. Using Microsoft 365 Admin Center
   The Microsoft 365 Admin Center does not provide a Private Teams report.

❌ Limitations

• No exclusive listing or filtering of Private Teams
• Privacy setting is visible, but cannot be set to filter only for “private teams”
• No centralized reporting or export


Admins must manually inspect each Team to check its visibility.

2. Using Microsoft Teams Admin Center
   The Microsoft Teams Admin Center offers more detail but still lacks reporting flexibility.

❌ Limitations

• No exclusive filter for Private Teams
• Privacy setting is displayed but not filterable
• Owners and members require manual inspection
• No consolidated export
• Report shareable via mail


This approach does not scale for large tenants.

3. Using Graph PowerShell
   Graph PowerShell allows admins to programmatically fetch only Private Microsoft Teams.

📘 Reference Script:

This approach typically:

• Retrieves Teams-enabled groups
• Filters Teams by visibility = Private
• Formats and exports the results

⚠️ Downsides of PowerShell

• Requires Graph and PowerShell expertise
• Script maintenance required
• Manual CSV formatting and export
• Not ideal for quick or recurring reporting

For many admins, this is unnecessary complexity for routine visibility tasks.
