Question details

The user wants to restrict the SharePoint People Picker to display only users who already have access to a specific restricted folder.

How to Limit SharePoint People Picker to Users with Folder Access

Product: Microsoft SharePoint
Device & OS: not provided
Scenario: Sharing documents or folders in a SharePoint environment with restricted access.
Observed behavior: SharePoint natively displays the entire organizational directory in the people picker, even when the current folder has restricted permissions, increasing the risk of selecting unauthorized users.

Before you start

Make sure you have Site Owner or Microsoft 365 Administrator privileges, as adjusting site-wide sharing policies and permissions requires advanced administrative access.

Solution 1Recommended

Review and Adjust SharePoint Site Sharing Permissions

Adjusting the site sharing settings prevents unauthorized users from gaining access even if they are accidentally selected in the people picker.

By default, SharePoint searches the entire global address list when typing in the people picker. While you cannot natively restrict the people picker dropdown strictly to folder members without custom development, you can lock down sharing settings so that accidentally selecting the wrong person does not grant them access.

Access Site Permissions

Click the gear icon (Settings) in the top right corner of your SharePoint site and select 'Site permissions'.

Modify Sharing Settings

Click 'Change how members can share' under the Site Sharing section.

Restrict Sharing Capabilities

Select 'Only site owners can share files, folders, and the site'. This ensures that even if a regular user selects someone from the people picker, an access request will be sent to the admin instead of automatically granting access.

Review Existing Folder Access

Navigate to the restricted folder, click the three vertical dots (More options), select 'Manage access', and verify that only the intended groups or individuals have direct access.

Review and Adjust SharePoint Site Sharing Permissions

People Picker Behavior: Selecting a person from the directory does not automatically grant them access to the folder. Access is only provided if the sharing link configuration allows it and the sharing action is completed.

Solution 2

Implement a Custom Directory via Power Apps

Use Microsoft Power Apps to replace the default SharePoint form with a custom interface that filters available users.

Frequently Asked Questions

Does selecting a user in the SharePoint People Picker automatically grant them access?

No, selecting a user in the people picker merely queues their name for the action. Access is only granted when you finalize the sharing action, provided that your site sharing settings allow you to share.

Can I hide the global address list from a specific SharePoint site?

Natively, the SharePoint people picker queries the entire organizational directory. Hiding specific users or restricting the global address list requires Exchange Admin Center adjustments or creating custom SharePoint forms using Power Apps.

How do I check who currently has access to a restricted SharePoint folder?

Navigate to the folder in your document library, click the 'Show actions' icon (three dots) next to the folder name, and select 'Manage access'. This panel displays all individuals and groups with current permissions.

Why can users share files with people outside the folder's permission group?

If the site sharing settings are set to allow members to share files and folders, they can generate sharing links for anyone in the organization. To stop this, a site owner must change the sharing settings to 'Only site owners can share files, folders, and the site'.
