Find your teams with private channels with PowerShell script

Scratching your head over finding a list of all your teams with private channels? Look no further than this PowerShell script! Finding the ideal solution to this problem has never been easier.

This PowerShell script helps users locate all teams with private channels by querying and checking each one. It produces a detailed output that includes each team and its private channels. It also offers lists of all channel members and owners.

The convenience of private channels in Teams

As you probably know, private channels are helpful for almost all organizations. They enable people to improve how they work by allowing them to:

  • Have a focused space to collaborate without having to create a separate team.
  • Easily create a private channel where they can discuss sensitive information, such as budgets, strategic goals, and similar. 

The challenge with private channels is that users can create them without any criteria, which can be problematic when it comes to Microsoft 365 governance, creating all kinds of issues. And since we know how it can be challenging to solve these issues, we’ve created a PowerShell script to help you when you need to find teams with private channels.

For your convenience, the output is displayed on the screen by default. You may also use one of the optional flags to export the result to CSV:

-ExportCSV (if set, this will automatically export the result to a CSV file. If no export path is set, it will export the file to %temp% folder)  

Example: Get-TeamsWithPrivateChannels.ps1 -ExportCSV  


Example: Get-TeamsWithPrivateChannels.ps1 -ExportCSV -ExportFilePath “C:Tempreport.csv”

Just focus on collaborating with your team while our script takes care of finding the private channels.
