Disabling Access Requests and Controlling Site Sharing with PowerShell

Introduction

In SharePoint Online, managing access requests and controlling site sharing settings is crucial for maintaining security and governance. In this article we will see how to disable access requests and site sharing permission settings for a SharePoint site using PowerShell.

What is PnP PowerShell?

PnP PowerShell is a popular PowerShell module that simplifies managing SharePoint and Office 365 environments, providing a seamless scripting experience for automating tasks and configurations.

Prerequisites:

• PnP PowerShell module installed
• Permissions: Ensure that you have the necessary permissions to modify site permissions settings from your SharePoint site
• Update the SharePoint site URL in the script

Step 1. Connect to your SharePoint site

To begin, establish a connection to your SharePoint site using the Connect-PnPOnline cmdlet. Provide the URL of your site and your credentials when prompted.

Connect-PnPOnline "https://yourdomain.sharepoint.com/sites/yoursitecollection" -Interactive

Step 2. Retrieve the Web

Next, we will retrieve the web object using below cmdlet. It will allow us to access and modify the web properties.

$Web = Get-PnPWeb

Step 3. Disable Access Requests

Access Requests settings enables users to request access to the SharePoint site if they don’t already have permissions. In this step, we’ll disable access requests by settings the ‘RequestAccessEmail’ property of the web object to empty string and call the ‘SetUseAccessRequestDefaultAndUpdate’ method to update the access request settings and save the changes using the Update method.

$Web.RequestAccessEmail = [string]::Empty
$Web.SetUseAccessRequestDefaultAndUpdate($False)
$Web.Update()
$Web.Context.ExecuteQuery()

Step 4. Disable Site Sharing Permission Settings:

In order to prevent non-owners from sharing the site, we’ll use below cmdlet to update the site sharing permission settings for non-owners.

Set-PnPSite -Identity "https:// yourdomain.sharepoint.com/sites/ yoursitecollection " -DisableSharingForNonOwners

Step 5. Disconnect from SharePoint site

Once the email is sent, it's a good practice to disconnect from the SharePoint site using the Disconnect-PnPOnline cmdlet.

Disconnect-PnPOnline

Complete script

#Step 1 Connect SharePoint site

$Web.Context.ExecuteQuery()

#Step 4 disable Site Sharing Permission Settings
Set-PnPSite -Identity "https://yourdomain.sharepoint.com/sites/ yoursitecollection" -DisableSharingForNonOwners

#Step 5 Disconnect SharePoint site
Disconnect-PnPOnline
