$UserName="[email protected]"
$Password ="Password goes here"
try{
#Setup Credentials to connect
$Credentials = New-Object Microsoft.SharePoint.Client.SharePointOnlineCredentials($UserName,(ConvertTo-SecureString $Password -AsPlainText -Force))
$context = New-Object Microsoft.SharePoint.Client.ClientContext($SiteUrl)
$context.Credentials = $credentials
#get the subsite
$web = $context.Web
$context.Load($web)
$context.ExecuteQuery()
#sharepoint online powershell remove subsite

How to Delete All subsites under a Site in SharePoint Online using PowerShell?
Let’s wrap the above script into a reusable function to delete subsites recursively in a site collection!
#Load SharePoint Online Assemblies
Add-Type -Path "C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\16\ISAPI\Microsoft.SharePoint.Client.dll"
Add-Type -Path "C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\16\ISAPI\Microsoft.SharePoint.Client.Runtime.dll"
#Variables for Processing
$SiteUrl = "https://portal.sharepoint.com/sites/Sales/apac/us/"
$UserName="[email protected]"
$Password ="password goes here"
#Function to delete a subsite and its all child sites
Function Remove-SPOWeb() {
param(
$WebURL = $(throw "Please Enter the Subsite URL to Remove:")
)
try{
#Setup Credentials to connect
$Credentials = New-Object Microsoft.SharePoint.Client.SharePointOnlineCredentials($UserName,(ConvertTo-SecureString $Password -AsPlainText -Force))
#Get Web information and subsites
$Context = New-Object Microsoft.SharePoint.Client.ClientContext($webURL)
$Context.Credentials = $credentials
#get the subsite
$web = $context.Web
$context.Load($web)
$Context.Load($web.Webs)
$Context.executeQuery()
#Iterate through each subsite in the current web
foreach ($Subweb in $web.Webs)
{
#Call the function recursively to process all subsites underneaththe current web
Remove-SPOWeb($Subweb.url)
}
#sharepoint online powershell delete web
$web.DeleteObject()
$context.ExecuteQuery()
Write-Host "SubSite Deleted:" $web.Title -foregroundcolor Green
}
catch{
write-host "Error: $($_.Exception.Message)" -foregroundcolor Red
}
}
#Call the function to remove subsite
Remove-SPOWeb -WebURL $SiteUrl

SharePoint Online PnP PowerShell to Remove Subsite
Here is how to delete subsite using PnP PowerShell.
#Config Variables
$SiteURL = "https://crescenttech.sharepoint.com/Sales"
$SubsiteURL = "2018" # Just URL of the Subsite under parent site - NOT Relative Path
#Get Credentials to connect
$Cred = Get-Credential
#Connect PnP Online to Parent Web
Connect-PnPOnline -Url $SiteURL -Credentials $Cred
#sharepoint online delete subsite powershell
Remove-PnPWeb -Url $SubsiteURL -Force
The Remove-PnPWeb cmdlet permanently removes a specific subsite. However, if your subsite has any child subsites, the script will end up in error saying:
Remove-PnPWeb : There was a problem deleting Web site “/sales”. Sites that have subsites or certain apps can’t be deleted. Please try again after deleting all subsites and removing the apps.

ForEach($SubWeb in $SubWebs)
{
#Call the function recursively to remove subsites

}
#Delete the subsite
