How to Restore Access to SharePoint Shared Libraries After a 404 Error

Product: Microsoft 365 SharePoint
Device & OS: not provided
Scenario: Accessing shared-library files or folders via Windows Explorer or an online browser.
Observed behavior: The system displays a 404 error page, indicating that the site, folder, or file may have been moved, deleted, or become unavailable.

Before you start

Verify that your internet connection is active and that you are signed into your Microsoft 365 account with the appropriate permissions to view the shared library.

Solution 1Recommended

Troubleshoot the Site URL and Check Recycle Bins

Use this method to determine if the specific file or folder was moved or deleted while the main SharePoint site is still active.

A 404 error often means the specific path you are trying to access no longer exists, but the parent site might still be intact. By isolating the root URL, you can navigate the site to find moved items or restore deleted ones.

Identify the root site URL

Look at the URL on the 404 error page in your web browser. Delete the specific file or folder path at the end of the URL to isolate the main SharePoint site address.

Open the root site

Press Enter to navigate to the shortened URL. If the main SharePoint site loads successfully, the site itself is active and the issue is isolated to the specific file or folder.

Review site activity

Navigate to 'Site contents' or check the recent activity pane on the home page to see if the missing folder or file was recently moved to a different location or renamed.

Check the SharePoint Recycle Bin

Click on 'Recycle bin' in the left-hand navigation pane. Search for your missing files or folders. If found, select them and click 'Restore' to return them to their original location.

Troubleshoot the Site URL and Check Recycle Bins

Tip for Site Collection Admins: If the file isn't in the standard Recycle Bin, site collection administrators can check the Second-stage recycle bin at the bottom of the Recycle Bin page.

Solution 2

Escalate to Your Microsoft 365 Administrator

Follow this step if the root SharePoint site fails to load or returns a 404 error itself.

Frequently Asked Questions

Why am I getting a 404 error in SharePoint when syncing with Windows Explorer?

A 404 error typically indicates that the file, folder, or the parent SharePoint site has been deleted, moved, or renamed since the last sync. It can also happen if your account's access permissions have been removed.

How long do deleted files stay in the SharePoint Recycle Bin?

By default, deleted files are retained in the SharePoint recycle bins for 93 days. If they are not restored within this time frame, they are permanently deleted.
