Fix SharePoint Users Losing Site Access After Changing Group Permissions

Product: Microsoft SharePoint
Device & OS: not provided
Scenario: Modifying SharePoint group permissions in an attempt to restrict certain user actions on a site.
Observed behavior: Users are completely locked out of the SharePoint site and prompted to request access, rather than just experiencing restricted capabilities on the site.

Before you start

Ensure you have Site Owner or Full Control permissions in SharePoint before attempting to modify group permission levels and inheritance settings.

Adjust Site-Level Permissions and Use Custom Permission Levels

Revert overly restrictive permissions at the site level and create custom permission levels to maintain basic site access while restricting specific actions.

Default restrictive permissions like 'Restricted View' or 'Restricted Read' can be too strict when applied at the top site level, often blocking users from loading necessary site components. To fix this, access should be restored, and restrictions should be applied more granularly.

Verify current permission levels

Navigate to Site Settings > Site permissions to check if 'Restricted View' or 'Restricted Read' is currently applied to the affected SharePoint group.

Restore standard access

Temporarily change the affected group's permission back to 'Read' so users can immediately regain basic site access without encountering the access request prompt.

Create a custom permission level

Go to Site permissions > Advanced permissions settings > Permission Levels. Create a new custom level based on 'Read' but uncheck specific actions (such as downloading or printing) according to your security needs.

Apply restricted permissions granularly

Instead of restricting the entire site, apply default restrictive permission levels only to specific document libraries or individual files by breaking their permission inheritance.

Contact Microsoft 365 administrator

If users continue to experience access failures after restoring 'Read' permissions, contact your Microsoft 365 administrator to review potential conditional access policies.

Best Practice for Restrictions: Always reserve highly restrictive permissions for specific libraries, folders, or files rather than the entire site collection to ensure site navigation and master pages remain accessible.

Frequently Asked Questions

What is the difference between Restricted Read and Restricted View in SharePoint?

Restricted Read allows users to view pages and documents but prevents them from downloading documents or viewing historical versions. Restricted View allows users to view documents in the browser but prevents them from downloading or printing, which typically requires specific server features.

Why does restricting permissions at the site level break user access entirely?

Site-level permissions control access to foundational elements of the SharePoint site, including navigation menus and master pages. Highly restrictive default levels block access to these essential background components, causing users to be completely locked out.

How do I break permission inheritance for a specific SharePoint document library?

Navigate to the specific library, click the Settings (gear) icon > Library settings > More library settings > Permissions for this document library. Click 'Stop Inheriting Permissions' in the top ribbon to apply unique permissions without affecting the entire site.

Can I test SharePoint permissions before applying them to a large group?

Yes, you can use the 'Check Permissions' button located in the Advanced permissions settings ribbon. This tool allows you to verify exactly what access a specific user or group will have on that site or library before finalizing your configuration.
