Question details

Users are experiencing access issues where permissions applied to a parent SharePoint folder do not cascade down to its subfolders.

How to Fix SharePoint Folder Permissions Not Inherited by Subfolders

Product: Microsoft SharePoint
Device & OS: not provided
Scenario: Managing document access and sharing nested folders within a Microsoft SharePoint site.
Observed behavior: Subfolders and their contents do not inherit the access rights granted at the parent folder level, causing Access Denied errors for authorized users.

Before you start

Verify whether the affected users are part of a Microsoft 365 group or a standard SharePoint group, and confirm if users are receiving specific 'Access Denied' errors when trying to open the subfolders.

Solution 1Recommended

Delete Unique Permissions and Restore Inheritance

Reconnect the subfolder to the parent folder's permission structure by deleting unique permissions, which forces it to inherit the parent access rights.

SharePoint permissions stop flowing downwards when a subfolder is given unique permissions. This often happens automatically if a subfolder or document was shared directly with a specific user. Restoring inheritance will wipe out those unique permissions and mirror the parent folder.

Navigate to the affected subfolder

Open your SharePoint document library and locate the specific subfolder that users cannot access.

Open the Manage Access panel

Click the three dots (ellipses) next to the folder name and select 'Manage Access' from the dropdown menu.

Access Advanced settings

Scroll to the bottom of the Manage Access panel and click on 'Advanced' to open the classic permissions page.

Delete unique permissions

If the folder has unique permissions, click the 'Delete unique permissions' button located in the ribbon at the top of the page.

Confirm inheritance restoration

Click 'OK' in the pop-up dialogue box to confirm. The folder will now display a message stating that it inherits permissions from its parent.

Delete Unique Permissions and Restore Inheritance

Permissions Restored: Any user with access to the parent folder will now be able to open and interact with this subfolder based on their parent-level rights.

Solution 2

Verify Group Types and Re-share the Parent Folder

Ensure that the folder was shared with the correct group type (Microsoft 365 vs SharePoint group) to prevent access conflicts.

Frequently Asked Questions

Why do SharePoint subfolders suddenly stop inheriting permissions?

Subfolders stop inheriting permissions when unique permissions are explicitly set on them. This frequently occurs when a file or subfolder is shared directly with an external user or someone who doesn't have access to the parent folder, which automatically breaks the inheritance chain.

How can I quickly check if a folder has unique permissions?

Select the folder in your SharePoint library, go to 'Manage Access', and click 'Advanced'. Look for a yellow banner or message at the top of the permissions page stating 'This folder has unique permissions' or 'This folder inherits permissions from its parent'.

Does generating a sharing link break permission inheritance?

Yes, depending on your SharePoint site's sharing settings, creating a specific custom sharing link for a subfolder or file can sometimes generate unique item-level permissions, thereby breaking its inheritance from the parent folder.

Can I bulk restore permission inheritance for multiple subfolders at once?

SharePoint's native web interface requires you to restore inheritance folder by folder. For bulk operations across multiple libraries or extensive folder structures, administrators typically need to use PowerShell scripts or specialized third-party SharePoint management tools.
