I was looking for a easy way to delete hundreds of test site in a modern SharePoint online env. MS flow didn't to the trick, so I was looking into PowerShell.

Set-Location -Path C:\scripts

#Connect to SPO
$tenantName= "companyName"
$username = "[email protected]"
$password = "SuperSavePassword" | ConvertTo-SecureString -AsPlainText -Force
$cred = New-Object System.Management.Automation.PSCredential -ArgumentList $Username,$Password

Connect-SPOService -Url https://$tenantName-admin.sharepoint.com/ -Credential $cred
Connect-MsolService -Credential $cred
Connect-AzureAD -Credential $cred
Connect-PnPOnline -Url https://$tenantName-admin.sharepoint.com/ -Credentials $cred 

Anytime I'm trying to Get-PnPUnifiedGroup I get an error saying s'thing like:

Get-PnPUnifiedGroup : Exception while invoking endpoint https://login.microsoftonline.com/2092f441-2e68-4313-9252-4794a2e05343/oauth2/token

Yet, my account is a global admin on the tenant.


I found another way, in which I don't have to use 'PNPunifiedGroup'

$sites= Import-Csv C:\Users\xxx\Downloads\DemoToDelete.csv
ForEach ($s in $sites)
$group = Get-MSolGroup -SearchString $s.Title
Remove-MsolGroup -ObjectId $group.ObjectId
Remove-SPOSite -Identity $s.SiteUrl -Confirm:$False

This deleted like 50% of the sites provided in .csv

You can delete the modern team site and associated groups as below using PnP PowerShell.

You first need to delete the SharePoint site collection and then remove the O365 group using the Graph endpoints by connecting to it via scopes

$tenantName= "companyName"
$username = "[email protected]"
$password = "SuperSavePassword" | ConvertTo-SecureString -AsPlainText -Force
$cred = New-Object System.Management.Automation.PSCredential -ArgumentList $Username,$Password

Connect-PnPOnline "https://tenant-admin.sharepoint.com" -Credentials $cred
Remove-PnPTenantSite https://tenant.sharepoint.com/sites/ModernTeamSite

Connect-PnPOnline "https://tenant-admin.sharepoint.com" -Scopes "Group.ReadWrite.All", "Directory.ReadWrite.All" -Credentials $cred
$unifiedGroup = Get-PnPUnifiedGroup -Identity "Group Name"
Remove-PnPUnifiedGroup -Identity $unifiedGroup.ID 

Reference - Delete an Office365 group and SharePoint site collection

  • Thanks for your fast reply. Unfortunately in SharePoint Online, first you have to delete the O365group and than the SPOsite. But I can't seem to get it working. I updated my code in the original post.

  • Did you try the code I posted ? In the get pnpunifiedgroup method, you need to pass display name of the group Jun 19, 2019 at 14:04
  • Yeah, but not quite what I'm looking for. Remove-PnPTenantSite doesn't work since the site is connected to a O365group. And I'm deleting like 100 sites, so I need to use a foreachloop, for which I only have the siteUrl...

  • @Emiel, If you are a global admin, use AzureAD PowerShell. The might be helpful:morgantechspace.com/2019/02/… Jun 19, 2019 at 20:16
  • @Emiel also curious why not just use the New Admin Centre where Groups are visiting and just select the test one and delete? Jun 19, 2019 at 20:17

And MS fixed it :-) SP-admin center now features "Bulk Edit" on active sites.

  • I think it kind of provide an answer... Since the ultimate script isn't necessary anymore and you simple can delete multiple SPO-sites through GUI..
