PowerShell script: What are my teams with shared channels

If you are trying to find a list of all your teams with shared channels then this PowerShell script is just what you need.

The script’s purpose is to find all teams with shared channels. The script gets all the teams, and it checks all channels for each team. It will output the team and any of the shared channels it has. By default, the script outputs the result only to the screen. There are optional flags you can use to export the result to CSV.  

-ExportCSV (if set, this will automatically export the result to a CSV file. If you don’t set an export path, it will export the file to %temp% folder)  

Example: Get-TeamsWithSharedChannels.ps1 -ExportCSV  

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

PowerShell Script code:

# Set script parameters
[CmdletBinding()]
param (
    [switch]$ExportCSV,
    [string]$ExportFilePath = "$env:TEMP\$(Get-Date -Format "yyyy_MM_dd")TeamsWithSharedChannels.csv"
)

# Check or install Microsoft Teams module
if ($null -eq (Get-Module -ListAvailable MicrosoftTeams)) {
    try {
        Write-Output "Microsoft Teams module not found. Trying to install"

        Install-PackageProvider -Name NuGet -MinimumVersion 2.8.5.201 -Force | Out-Null
        Install-Module MicrosoftTeams -Force | Out-Null
        Write-Output "Microsoft Teams module installed"
    }
    catch {
        Write-Output "Unable to install Microsoft Teams module. $($Error[0].Exception.Message)"
        Return
    }

                    MembershipType = $SingleChannel.MembershipType
