Question details

Users need a solution to ensure that changes made to a user's permission level apply correctly to all subfolders, including those that possess unique, broken inheritance permissions.

How to Fix SharePoint Permissions Not Propagating to Unique Subfolders

Product: SharePoint
Device & OS: not provided
Scenario: Managing access controls and updating user permissions for SharePoint libraries that contain subfolders with unique permissions.
Observed behavior: When changing a user's permission level in the Advanced settings, the updates fail to propagate to subfolders that have unique permissions, resulting in inconsistent access rights across the library.

Before you start

Ensure you have Site Owner or Full Control administrative privileges in your SharePoint environment to create custom permission levels and modify library inheritance settings.

Solution 1Recommended

Create and Assign a Custom Combined Permission Level

Combining multiple required permissions into a single custom level allows you to grant comprehensive access that propagates reliably to all items, including subfolders with unique permissions.

By default, assigning secondary permission roles might only apply to subfolders that inherit permissions. Building a custom role bypasses this limitation without requiring complex PowerShell scripts.

Create a new custom permission level

Navigate to 'Site Settings' > 'Site Permissions' > 'Permission Levels'. Click 'Add a Permission Level', provide a descriptive name, and check all the individual permissions the user requires.

Navigate to Library Advanced Settings

Go to the specific Document Library you want to manage. Click the gear icon, select 'Library settings', then click 'More library settings', and choose 'Permissions for this document library'.

Grant the custom permission level

Click 'Grant Permissions' and enter the user's name. Click 'Show options', select the new custom permission level you created, and ensure you choose the option to share everything in the folder, including items with unique permissions.

Create and Assign a Custom Combined Permission Level

Updating Future Permissions: If the user's access level needs to change again in the future, it is highly recommended to completely remove their existing permission first, and then re-invite them with the newly adjusted permission level.

Solution 2

Manually Update Permissions for Specific Subfolders

Use this method if your organization requires completely different permission configurations for different unique subfolders, preventing the use of a unified custom permission level.

Frequently Asked Questions

Why do some SharePoint subfolders ignore permission updates applied to the parent library?

If a subfolder has been set to 'Stop Inheriting Permissions', it acts independently from its parent folder. General permission updates applied at the library level will not automatically cascade down to items with unique permissions unless explicitly pushed during the sharing process.

Can I grant multiple permission levels at once to force access propagation?

While you can grant multiple roles to a user, SharePoint often applies secondary permissions only to items that inherit access. Creating a unified, custom permission level that consolidates all necessary rights is the most reliable way to ensure access propagates to unique subfolders.

Does this permission management method require PowerShell scripting?

No, creating a custom permission level and assigning it via the Advanced Permissions menu can be completed entirely through the standard SharePoint web interface without needing any PowerShell commands.
