Teams が有効な Office 365 グループを取得したい

こんにちは、Teamsサポートの吉野です。
本日は便利なスクリプトを紹介させていただきます。

「現在作成されているチームの一覧を取得したい」という要望があるかと思います。
実はこちら、標準の機能では実装しておりません。
例えば管理者権限で Get-Team を実行してもそのユーザーが所属しているチームの一覧しか取得できません。

テナント全体のチーム一覧は以下のようなスクリプトで取得する必要があります。

Microsoft Teams Enabled O365 Groups Report PowerShell CSV Output

こちら大変便利なのですが、試してみたところ日本語が文字化けすることが分かりました。
日本語対応してみましたのでご活用いただければと思います。

## Microsoft Teams O365 Group Enabled Teams Reporting Script
## Created and edited by Sam Cosby - Microsoft & David Whitney - Microsoft
## 2/2/2018


## Require PowerShell Admin

If (-NOT ([Security.Principal.WindowsPrincipal] [Security.Principal.WindowsIdentity]::GetCurrent()).IsInRole(`
    [Security.Principal.WindowsBuiltInRole] "Administrator"))
{
    Write-Warning "`nYou do not have Administrator rights to run this script!`nPlease re-run this script as an Administrator!"
    Break
}

## Connect to EXO

$shell = new-object -comobject "WScript.Shell"
$result = $shell.popup("Do your Admin Credentials require MFA?",0,"Question",4+32)
if ($result -eq "6") { 
Write-Host "You must connect via the Exchange Online MFA Powershell module. To learn more on this, please use the following: https://technet.microsoft.com/en-us/library/mt775114(v=exchg.160).aspx"
break;
}


if (-not (Get-PSSession | where {($_.ComputerName -eq "outlook.office365.com") -and ($_.State -eq "Opened")}))
    {
Write-Output "#######################################################


Please connect with your Exchange Online Administrator Credentials in order to finish the rest of the script.

    $cred = get-credential

    Import-PSSession $Session -WarningAction SilentlyContinue
   }

## Connect to Microsoft Teams

if (Get-Module | where {($_.Name -eq "MicrosoftTeams") -and (($_.Version -eq "0.9.1") -or ($_.Version -eq "0.9.0"))}) {"Teams PowerShell is connected"}
    elseif (Connect-MicrosoftTeams -Credential $cred){"Teams Powershell needs connected"}
    else {Write-Output "You need to install the Microsoft Teams module. To do so, input 'install-module MicrosoftTeams' in Powershell as an Administrator"}


## Run the script to gather the list of Teams.

This may take a little bit of time... Please sit back, relax and enjoy some GIFs inside of Teams!
