Microsoft 365 Apps - Teams not installed (Using Company Portal)

# Define the path where New Microsoft Teams is installed
$teamsPath = "C:\Program Files\WindowsApps"

# Define the filter pattern for Microsoft Teams installer
$teamsInstallerName = "MSTeams_*"

# Retrieve items in the specified path matching the filter pattern
$teamsNew = Get-ChildItem -Path $teamsPath -Filter $teamsInstallerName

# Check if Microsoft Teams is installed
if ($teamsNew) {
# Display message if Microsoft Teams is found
Write-Host "New Microsoft Teams client is installed."
exit 0
} else {
# Display message if Microsoft Teams is not found
Write-Host "Microsoft Teams client not found."
exit 1
}

I think because 365 Apps was device pushed it had no license, so didn't install Teams. This way installs it like any other app, you just need to keep the bootstrapper up to date. This way will keep the latest Teams installing for each build though.
