How to Manage Access Requests for SharePoint Document Libraries
Question details
The user wants to know if they can set up an access request and approval workflow specifically for a SharePoint document library, similar to how it natively works for a whole SharePoint site.

- Product
- SharePoint Online
- Device & OS
- not provided
- Scenario
- Setting up specific access control and formal request workflows for individual document libraries instead of entire sites.
- Observed behavior
- While unique permissions can be set by breaking inheritance, the native site-level access-request workflow does not automatically apply to individual document libraries.
Ensure you have Site Owner or Full Control permissions on the SharePoint site to modify library settings, break inheritance, and configure Power Automate workflows.
Set Up a Custom Access Request Workflow with Power Automate
Since native access requests aren't supported directly at the library level, build a custom request form and approval flow using Microsoft 365 tools.
If you restrict permissions to a library, users without access simply won't see the documents and won't receive an access request prompt. To establish a formal request workflow, you can combine a custom form with a Power Automate flow to notify owners and grant access.
Use Microsoft Forms, Power Apps, or a custom SharePoint List to create a form where users can submit their request to access the specific document library.
Open Power Automate and create an automated cloud flow that triggers when a new response or item is submitted to your request form.
Add the 'Start and wait for an approval' action. Assign the library owners or administrators as the approvers for the request.
Add a Condition based on the approval outcome. If approved, add the 'Grant access to an item or a folder' SharePoint action to automatically provide the user with the correct permissions.

Configure Unique Permissions for the Document Library
Break permission inheritance to manually control exactly who has access to the specific document library.
Try WPS Office for Seamless Document Management

Frequently Asked Questions
Why don't access requests work for document libraries like they do for sites?
SharePoint's native access request feature is designed to function at the site collection and site level. Document libraries rely on inherited site permissions by default. Even when inheritance is broken, restricted libraries do not trigger the site's native access request email system.
What happens when a user tries to access a restricted document library?
If a user has access to the main SharePoint site but not to a specific restricted library, the library simply won't be visible to them in the site navigation or site contents. They will not get an 'Access Denied' prompt with a built-in request button.
Can I use Microsoft Forms to manage SharePoint access requests?
Yes, you can create a Microsoft Form for users to fill out when they need access, and link it to a Power Automate flow that alerts the administrator and automatically grants access upon approval.
Is there a way to mimic the Access Denied page for SharePoint libraries?
As a workaround, you can create a custom SharePoint page that acts as an access request hub with links to request forms for specific libraries, and direct users to this page when they need access to restricted content.
