Streamline SharePoint File Permissions Management with PowerShell

SharePoint & OneDriveJanuary 4, 2025

Managing file and folder permissions in SharePoint can often be complex and time-consuming. Using PowerShell, you can automate this process, making it easier to handle permissions on SharePoint document libraries and lists. This PowerShell script will help you grant specific permissions to a SharePoint group for a given document library.

powershell

# Install the SharePoint Online Management Shell if not already installed
Install-Module -Name "Microsoft.Online.SharePoint.PowerShell" -Force
# Connect to SharePoint Online
$siteUrl = "https://yourtenant.sharepoint.com/sites/yoursite"
Connect-SPOService -Url $siteUrl

# Specify the group and document library
$groupName = "Your SharePoint Group"  # Replace with your group name
$documentLibrary = "Documents"          # Replace with your document library name

# Get the group
$group = Get-SPOSiteGroup -Site $siteUrl -Group $groupName
# Check if permissions are already set
$roleAssignments = Get-SPOSiteGroup -Site $siteUrl -Group $groupName

# Granting permissions to the document library
$roleDef = "Contribute"  # Example: Contribute permission
Set-SPOSiteGroup -Site $siteUrl -Group $groupName -AddRoleAssignment $roleDef -List $documentLibrary
