How to Fix SharePoint Site Sharing When Advanced Permissions Are Required
Question details
Users are unable to share a SharePoint communication site because the system prompts that it has unique permissions and requires Advanced permissions settings.

- Product
- Microsoft SharePoint
- Device & OS
- not provided
- Scenario
- A site owner or administrator is attempting to share a SharePoint communication site with new users.
- Observed behavior
- The standard sharing controls are missing, and a message appears stating the site must be shared through Advanced permissions settings, often due to missing default SharePoint groups.
Ensure you are logged in with an account that has Site Owner or Full Control administrator rights on the affected SharePoint communication site.
Verify and Restore Default SharePoint Permission Groups
Check for missing default SharePoint groups (Owners, Members, Visitors) in the advanced settings and restore them to enable standard site sharing capabilities.
SharePoint communication sites rely on default permission groups to manage sharing controls. If these groups are deleted or modified, the site defaults to requiring advanced permissions to prevent unauthorized access.
Navigate to your SharePoint site, click the gear icon (Settings) in the top-right corner, and select 'Site permissions' from the dropdown menu.
In the Site permissions panel, scroll to the bottom and click on the 'Advanced permissions settings' link.
Review the list of groups to ensure that the default Site Owners, Site Members, and Site Visitors groups exist and contain the appropriate users.
If the default groups are missing, click 'Create Group' on the ribbon, name them appropriately, and assign the correct permission levels (Full Control, Edit, Read). Add the required users to these restored groups.
Return to the main SharePoint site homepage and click the 'Share' button to verify that standard sharing functionality has been restored.

Simplify Document Collaboration with WPS Office
While SharePoint handles complex site infrastructures, you can streamline your team's document collaboration with WPS Office. It provides a lightweight, highly compatible, and easy-to-use alternative to Microsoft Office for creating, editing, and sharing documents without dealing with convoluted permission hierarchies.
- 1. Download the Installer: Visit the official WPS website and download the free installation package for your operating system.
- 2. Install and Launch: Run the installer and follow the on-screen instructions to set up WPS Office on your device.
- 3. Collaborate Instantly: Open any Office document, click the 'Share' button in the top right corner, and generate a secure link to collaborate with your team.

Frequently Asked Questions
Why is my SharePoint site asking for Advanced permissions when I try to share it?
This typically occurs when the default permission groups (Owners, Members, Visitors) have been removed or when unique permissions have been heavily applied to the site's root level, forcing the system to fall back to advanced controls.
Does breaking inheritance on a document library prevent site sharing?
No. Normally, breaking permissions on a specific page, list, or document library only affects that specific element. It does not prevent you from sharing the entire SharePoint site.
How do I access Advanced permission settings in SharePoint?
Click the Settings (gear) icon in the top right corner of your SharePoint site, select 'Site permissions', and then click the 'Advanced permissions settings' link located at the bottom of the panel.
