Delete SharePoint Online site collections using powershell

Question

Hello,

I have been trying to delete site collections from a csv, I'm trying to use a powershell script to get the site URLs to be deleted.

I've tried everything, now that I've run out of ideas I'm opening this question. I'm accepting possibilities other than Powershell

PS: I'm trying to do this without creating anything in the tenant.

This site belongs to a Microsoft 365 group. To delete the site, you must delete the group.

Below are some attempts:

#Modules  
Import-Module ExchangeOnlineManagement  
Import-Module Microsoft.Online.SharePoint.PowerShell  
Import-Module SharePointPnPPowerShellOnline  
      
$site = "https://tenant.sharepoint.com/sites/site"  
$mailGroup = "******@onmicrosoft.com"  
      
#First  
Remove-UnifiedGroup -Identity $mailGroup-Confirm:$false  
Remove-SPOSite -Identity $site -NoWait -Confirm:$false  
      
#Second  
Remove-UnifiedGroup -Identity $mailGroup-Confirm:$false  
      
Set-SPOSite -Identity $site  -LockState "unlock"   
Set-SPOSite -Identity $site  -Owner $userCredential.UserName  
Remove-SPOSite -Identity $site -NoWait -Confirm:$false  
      
#Third  
$SharepointSite = Get-SPOSite $site  
Remove-PnPUnifiedGroup -Identity $SharepointSite .GroupID  
Remove-PnPTenantSite $site  

I also tried what is in the link: https://learn.microsoft.com/en-us/answers/questions/674248/batch-delete-site-collections-in-powershell-from-c.html

Hi @Hoke ,

You could delete the group associated with the site collection. After deleting the Microsoft 365 group, you should wait for a while and the site will be automatically deleted.

PowerShell command:

#Parameters  
$AdminCenterURL="https://tenant-admin.sharepoint.com"  
$GroupSiteURL="https://tenant.sharepoint.com/sites/site"  
  
#Connect to SharePoint Online  
Connect-SPOService -Url $AdminCenterURL  
  
#Unlock the Group site Collection  
Set-SPOSite -Identity $GroupSiteURL -LockState unlock  
  
Remove-UnifiedGroup -Identity "group name"
