Microsoft 365 Free Reporting Tool – Teams With Private Channels Report

Private channels in Microsoft Teams provide restricted collaboration within a Team. While they are powerful for handling sensitive discussions, they also introduce additional governance complexity.

Many administrators eventually ask: Which Teams in my tenant contain Private Channels?

Unfortunately, getting a clear answer using native tools is not straightforward.

The Teams With Private Channels Report, available in the M365 Free Reporting Tool, gives administrators instant visibility into Teams that contain private channels — without scripting or manual filtering.

How to Generate Teams With Private Channels Report?

Let’s examine the available approaches and their limitations.

1. Using Microsoft 365 Admin Center

The Microsoft 365 Admin Center does not provide any visibility into private channel usage.

❌ Limitations

• No support for identifying Teams with Private Channels
• No reporting or filtering options
• No visibility into channel types

This method is not suitable for private channel monitoring.


2. Using Microsoft Teams Admin Center

The Microsoft Teams Admin Center offers limited visibility.

Admins can:

• Add the Private Channels column to the Teams list

However:

❌ Limitations

• Teams with 0 private channels are still shown
• No exclusive filtering for Teams that actually contain private channels
• Results require manual inspection
• No clean export view


In large tenants, this becomes time-consuming and inefficient.

3. Using Graph PowerShell

Graph PowerShell allows administrators to programmatically identify Teams that contain private channels.

Sample Graph PowerShell Script

                                                
# Connect to Microsoft Graph
Connect-MgGraph -Scopes "Group.Read.All","Channel.ReadBasic.All"

# Get all Teams-enabled groups
$teams = Get-MgGroup -All `
    -Filter "resourceProvisioningOptions/Any(x:x eq 'Team')" `
    -Property Id, DisplayName

$report = foreach ($team in $teams) {

    $channels = Get-MgTeamChannel -TeamId $team.Id -All -ErrorAction SilentlyContinue
    $privateChannels = $channels | Where-Object { $_.MembershipType -eq "private" }

    if ($privateChannels.Count -gt 0) {
        [PSCustomObject]@{
            TeamName = $team.DisplayName
            TeamId   = $team.Id
            PrivateChannelCount = $privateChannels.Count
        }
    }
}

$report | Export-Csv "C:\TeamsWithPrivateChannels.csv" -NoTypeInformation
                                                
                                            

What this script does

• Retrieves all Teams-enabled groups
• Fetches channels for each Team
• Filters channels where MembershipType = private
• Outputs only Teams that contain private channels

⚠️ Downsides of PowerShell

• Requires Graph and PowerShell expertise
• Multiple API calls per Team
• Script maintenance required
• Manual formatting and export
• Not ideal for quick governance checks

While powerful, this approach adds complexity for routine reporting.
