Fix “List cannot be deleted while on hold or retention policy” Error on SharePoint Online
Problem: When trying to delete a document library in SharePoint Online, it gave an error message “list cannot be deleted while on hold or retention policy.”
Solution:
As the error message says: List cannot be deleted while on hold or retention policy, this error is due to the site is under hold or retention policy. So, to delete the list you must delete all its files and sub-folders first. Otherwise, you should remove the retention policy under Office 365 compliance center. You can quickly check if the site is under hold by going to:
- Admin centers >> Security & Compliance >> Search & investigation
- Click on eDiscovery, check if you have created any case. >> If you see any case, click Open
- Under Hold, Check if you see any site.
Deleting files at each folder could be haunting especially when you have a deep folder structure. Fortunately, we’ve PowerShell to relive the burden.

Delete Document Library in Retention Hold using PnP PowerShell
Let’s fix the “list cannot be deleted while on hold or retention policy” error on SharePoint Online by deleting all files and folders first and then the document library using PnP PowerShell.
#Parameters
$SiteURL = "https://crescent.sharepoint.com/sites/Marketing"
$ListName = "Branding Templates"
#Connect to the Site
Connect-PnPOnline -URL $SiteURL -Credentials (Get-Credential)
#Get the web & document Library
$Web = Get-PnPWeb
$List = Get-PnPList -Identity $ListName
#Function to delete all Files and sub-folders from a Folder
Function Empty-PnPFolder([Microsoft.SharePoint.Client.Folder]$Folder)
{
#Get the site relative path of the Folder
If($Folder.Context.web.ServerRelativeURL -eq "/")
{
$FolderSiteRelativeURL = $Folder.ServerRelativeUrl
}
Else
{
$FolderSiteRelativeURL = $Folder.ServerRelativeUrl.Replace($Folder.Context.web.ServerRelativeURL,[string]::Empty)
}
#Get All files in the folder
$Files = Get-PnPFolderItem -FolderSiteRelativeUrl $FolderSiteRelativeURL -ItemType File
#Delete all files in the Folder
ForEach ($File in $Files)
{
#Delete File
Remove-PnPFile -ServerRelativeUrl $File.ServerRelativeURL -Force -Recycle
Write-Host -f Green ("Deleted File: '{0}' at '{1}'" -f $File.Name, $File.ServerRelativeURL)
}
#Process all Sub-Folders
$SubFolders = Get-PnPFolderItem -FolderSiteRelativeUrl $FolderSiteRelativeURL -ItemType Folder
Foreach($SubFolder in $SubFolders)
{
#Exclude "Forms" and Hidden folders
If( ($SubFolder.Name -ne "Forms") -and (-Not($SubFolder.Name.StartsWith("_"))))
{
#Call the function recursively
Empty-PnPFolder -Folder $SubFolder
#Delete the folder
Remove-PnPFolder -Name $SubFolder.Name -Folder $FolderSiteRelativeURL -Force -Recycle
Write-Host -f Green ("Deleted Folder: '{0}' at '{1}'" -f $SubFolder.Name, $SubFolder.ServerRelativeURL)
}
}
}
#Get the Root Folder of the Document Library and call the function to empty folder contents recursively
Empty-PnPFolder -Folder $List.RootFolder
#Now delete the document library
Remove-PnPList -Identity $ListName -Recycle -Force
Write-host -f Green "Document Library Deleted Successfully!"
If just want to clear the document library, without deleting the library too, just comment the line#50 – Remove-PnPList.
