Posted on Updated on

If you are involved in rolling-out of Microsoft Teams or groups recently, then you may need a test script to create temporary O365 Groups
Using the below PowerShell script, you will be able to do so

Pre-requisites:
——————
You should have :

  1. Client Id
  2. Client Secret
  3. tenant admin Url & Credentials

function Test-Group {
##Get Access Token
$body = @{
scope="https://graph.microsoft.com/.default";
client_id=$AppID;
client_secret=$AppSecret;
grant_type="client_credentials";
}
$accessToken = (Invoke-RestMethod `
-Uri https://login.microsoftonline.com/$AADDomain/oauth2/v2.0/token `
-Method POST `
-Body $body `
-Headers @{"Accept" ="application/json"; "Content-Type"="application/x-www-form-urlencoded"}).access_token
##Create Group
$body = @{
displayName="$prefix$suffix";
description="$prefix$suffix";
groupTypes= @("Unified");
mailEnabled="true";
mailNickname="$prefix$suffix";
securityEnabled="false";
visibility="Private";
#"owners@odata.bind"=@("https://graph.microsoft.com/v1.0/users/5a97df74-a0c9-4fb9-8f9f-26bd29d4bf06");
}| ConvertTo-Json
$NewGroup = (Invoke-WebRequest `
-Uri https://graph.microsoft.com/v1.0/groups `
-Method POST `
-Body $body `
-Headers @{"Authorization" = "Bearer $accessToken"; "Accept" ="application/json"; "Content-Type"="application/json"} )
$NewGroupId = ($NewGroup.Content | ConvertFrom-Json).Id
##Check if group was provisioned
$success = $false
$time = [System.Diagnostics.Stopwatch]::StartNew()
for ($i=0; $i -lt 60; $i+=5) {
Start-Sleep -s 5
try{
Invoke-WebRequest `
-Uri https://graph.microsoft.com/v1.0/groups/$NewGroupId/drive `
-Headers @{"Authorization" = "Bearer $accessToken"; "Accept" ="application/json";} | Out-Null
$success = $true
break
}catch [System.Net.WebException]{
If ($_.Exception.Response.StatusCode.Value__ -ne 404){
throw
}
}
}
if($success){
##Delete Group, you can leave it or keep it based on your needs
# Invoke-RestMethod `
# -Uri https://graph.microsoft.com/v1.0/groups/$NewGroupId `
# -Method Delete `
# -Headers @{"Authorization" = "Bearer $accessToken"; "Accept" ="application/json";} | Out-Null
} else {
Write-Host ModernGroup failed to provision in ([Math]::floor($time.Elapsed.TotalSeconds)) seconds -ForegroundColor Red
Write-Host GroupId: $NewGroupId -ForegroundColor Red
Write-Host CorrelationId: $NewGroup.Headers.'request-id' -ForegroundColor Red
Write-Host Date: $NewGroup.Headers.'Date' -ForegroundColor Red
}
}
$AppID = 'xxxxxxx-xxxx-xxxx-xxxxx-xxxxxxxxxxxx' #Put your AppId
$AppSecret = '**********************************' #Put your Secret
$AADDomain = 'yourtenant.onmicrosoft.com'
for ($i=0; $i -lt 1; $i++) {
$suffix = (Get-Date).Ticks
$prefix = "MSFT_Test_"
Test-Group
}

At the End you will have a test group created
