Hello Guys,

I recently had a situation where the user accidentally deleted big amount of files from SharePoint Online (about 10k). Restore them all manually would be a nightmare. So, I came up with a PowerShell script that I could inside SharePoint restore all items from Recycle bin with PowerShell
Looking around the Internet for a solution I found a few related articles but provided solutions either didn’t work or worked just for the on-prem environment.

So, I developed my own PowerShell script. Probably someone can found it useful as well.

Requirements

• Installed Management Shell Online

• Installed SharePoint Online Assemblies

• Site Collection Admin rights

Solution

All right, the solution is pretty simple, just copy the script provided below and paste to the new PowerShell file.

I configured script to be executed from a 2nd Admin Recycle bin.
If you would like to restore items from a 1st level Recycle bin change line #19 to the Web instead of Site:

$Site = $ctx.Web

Here is the script itself:

#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"
    
#Credentials
$SiteUrl = "https://bainbridgere.sharepoint.com/sites/SharePoint"
$UserName="apashkevych@bainbridgere.com"
 
#Set the password to connect
$Password = ConvertTo-SecureString "P@ssword2018!" -AsPlainText -Force
$Credentials = New-Object Microsoft.SharePoint.Client.SharePointOnlineCredentials($UserName,$Password)
  
Try {   
    #Setup the context
    $ctx = New-Object Microsoft.SharePoint.Client.ClientContext($SiteUrl)
    $ctx.Credentials = $Credentials
     
    #Get the web recycle bin
    $Site = $ctx.Site
    $RecycleBinItems = $Site.RecycleBin
    $ctx.Load($Site)
    $ctx.Load($RecycleBinItems)
    $ctx.ExecuteQuery()
 
    #Get all Excel files from Recycle bin
    $AllItems= $RecycleBinItems
    Write-Host "Total Number of Files found in Recycle Bin:" $AllItems.Count
     
    #Restore from Recylce bin
    $RecycleBinItems.RestoreAll()
	$ctx.ExecuteQuery()   
	
}
catch {
    write-host "Error: $($_.Exception.Message)" -foregroundcolor Red
}

Good luck with applying the script and restoring items.
