SharePoint - Remove Folder Permissions using Powershell

Question

_{Monday, July 9, 2018 2:56 PM}

Hi,

I am trying to pull together a script that will iterate through a library and remove and grant permissions on a folder with a specific name in a library.

I have the following script which works with granting permissions, but won't 'remove' permissions on the folder:

Add-PSSnapin Microsoft.SharePoint.PowerShell

# URL of Site
$PrivateGroup="DB Private"
$RemovalGroup1="Team-Test Members"
$PermissionLevel="Contribute"
$web = Get-SPWeb -Identity "http://teams-test.com/it/team-test"
$folderName = "ZZTest"

# Name of the list
$list = $web.Lists["Locations"]

$folders = $list.Folders
foreach($folder in $folders)
{
    if($folder.name -eq "ZZTest")
        {         
                    Write-Host $folder.name
         $folder.BreakRoleInheritance($true)
                     
                    #Get Group
                    $AddGroup = $Web.SiteGroups[$PrivateGroup]
                    $roleAssignment = new-object Microsoft.sharepoint.SPRoleAssignment($AddGroup)
                    $RemGroup = $web.SiteGroups[$RemovalGroup1]
                    $RoleRemoval = new-object Microsoft.sharepoint.SPRoleAssignment($RemGroup)
                                                                               
                    #Get Permission Level
                    $roleDefinition = $web.RoleDefinitions[$PermissionLevel]
                    $roleAssignment.RoleDefinitionBindings.add($roleDefinition);
                    $RoleRemoval.roledefinitionBindings.add($roleDefinition);                    
                                                            
                    #RemoveGroup                
                    $folder.RoleAssignments.Remove($RoleRemoval)
                    $folder.SystemUpdate();                                                                    

                    #Grant Access to Group
                    $folder.RoleAssignments.Add($roleAssignment)
                    $folder.SystemUpdate();     
            }
       }                 
$web.Dispose()
#

I get the following error on the "Remove"

Cannot find an overload for "Remove" and the argument count: "1".

At D:\Powershell\GetFolders.ps1:32 char:21

+ $folder.RoleAssignments.Remove($RoleRemoval)

+                     ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

+ CategoryInfo : NotSpecified: (:) [], MethodException

    + FullyQualifiedErrorId : MethodCountCouldNotFindBest

Any ideas or advice would be appreciated!

Thanks

I managed to get the above code working to Add group, and remove a group.

Hi Ethan,

Thanks for your reply, on reviewing the script it doesn't help my situation as I am trying to "Remove" permissions after "Granting Permission".

As per my original post, the "Grant Permission" step is working fine, it's the remove of the permissions I can't get to work?

Thanks

Matt
