Solution 1Recommended

Republish the Renamed Home Page

Republishing the page forces SharePoint to refresh the URL mapping, effectively restoring access to the renamed site or page.

When a SharePoint site or specific page is renamed, the underlying URL address often changes. If users try to access the site using cached links or old bookmarks, the server cannot locate the new path, resulting in a 404 error. Republishing the page is a quick way to synchronize the new name with the active URL.

Access Site Contents

Navigate to your SharePoint site settings (usually the gear icon) and select 'Site contents' from the menu.

Open the Site Pages Library

In the Site contents section, locate and click on the 'Site Pages' library to view all pages associated with your communication site.

Edit and Republish the Page

Find the renamed home page in the list. Click on it to open it, select 'Edit' at the top right, make a minor superficial change if needed to enable saving, and then click the 'Republish' button.

Update Bookmarks and Links

Test the site using the newly generated URL. Make sure to update any saved bookmarks, shared links, or navigation menus that are still pointing to the old web address.

Access Restored: Once the page is republished, the 404 error should disappear immediately upon navigating to the updated page link.

Frequently Asked Questions

Why does renaming a SharePoint site cause a 404 error?

Renaming a SharePoint site or page can change its web address (URL). If users attempt to access the site using an old link or bookmark, the server cannot find the new file path, resulting in a 404 Not Found error.

Will SharePoint automatically redirect old URLs to the new ones?

When a site address is officially changed through the SharePoint admin center, SharePoint usually creates a redirect from the old URL to the new one. However, renaming just a page title or using certain manual methods might break links, requiring you to manually republish the page.

How long does it take for a SharePoint site rename to fully take effect?

Generally, a site rename processes quickly, but it can take a few minutes to several hours for the changes to sync completely across all Microsoft 365 services and for the internal search index to update.
