Need to Remove multiple users from multiple Document librarys using CSOM/ Powershell script

Question

Hi Team,

We have multiple Document libraries having unique permissions each in SPO.

I need to remove users from those Libraries. Doing manually by going to each site one by one taking lot of time

Can some assist using CSOM or PowerShell to remove users for each respective Library by passing excel Input with user ID and SP Doc would be helpful.

Hi @Ganesh ，
The following script will use PSExcel to read excel data like the pic

Install-Module PSExcel  
  
$path = "c:\document\SPuser.xlsx"  
  
import-module psexcel #it wasn't auto loading on my machine  
  
#Connect PnP Online  
Connect-PnPOnline -Url $SiteURL -Credentials (Get-Credential)  
  
$file=Import-XLSX -Path $path -RowStart 1  
foreach ($user in $file){  
#Config Variables  
$SiteURL = "https://xxx.sharepoint.com/sites/test"  
$ListName = $user.Library  
$UserID= $user.UserID  
   
#Get the Context  
$Context = Get-PnPContext  
    
#Get the list & User objects  
$List = Get-PnPList -Identity $ListName  
$User = Get-PnPUser -Identity $UserID  
   
#Break Permission Inheritance  
Set-PnPList -Identity $ListName -BreakRoleInheritance -CopyRoleAssignments  
   
#Remove User from List Permissions  
$List.RoleAssignments.GetByPrincipal($User).DeleteObject()  
$Context.ExecuteQuery()  
  
}

You can use csom to access sharepoint by following script. The UserID in excel should change to logon name like ******@abc.com

$path = "c:\document\SPuser.xlsx"  
  
import-module psexcel #it wasn't auto loading on my machine  
  
$SiteURL = "https://xxx.sharepoint.com/sites/test"  
$Cred = Get-Credential  
$Cred = New-Object Microsoft.SharePoint.Client.SharePointOnlineCredentials($Cred.UserName,$Cred.Password)  
    
$file=Import-XLSX -Path $path -RowStart 1  
foreach ($user in $file){  
#Config Variables  
  
$ListName = $user.Library  
$UserAccount= $user.UserID  
   
$Ctx = New-Object Microsoft.SharePoint.Client.ClientContext($SiteURL)  
$Ctx.Credentials = $Cred  
        
#Get the List  
$List=$Ctx.Web.Lists.GetByTitle($ListName)  
$Ctx.Load($List)  
$Ctx.ExecuteQuery()  
           
#Get the User  
$User = $ctx.Web.EnsureUser($UserAccount)  
$Ctx.Load($User)  
$Ctx.ExecuteQuery()  
    
#Break Permission Inheritance  
$List.BreakRoleInheritance($true, $false)  
$Ctx.ExecuteQuery()  
   
#Get List Permissions  
$Ctx.Load($List.RoleAssignments)  
$ctx.ExecuteQuery()  
           
#Remove Group from List Permissions  
$List.RoleAssignments.GetByPrincipal($User).DeleteObject()  
$Ctx.ExecuteQuery()  
    
write-host  -f Green "User '$UserAccount' has been Removed from List '$ListName'"  
}
