“Invalid URL” error when you click a SharePoint Online Promoted Link which uses the file:// protocol


Consider the following scenario:

  • On a SharePoint Online site, you have a Promoted Links list.
  • Within the Promoted Links list, you create a link to a local file that uses the file:// protocol.

In this scenario, when you view the Promoted Links list in the tile view and then click the link that you created, you receive the following error message: 

Invalid URL

This is expected behavior in SharePoint Online. This issue occurs because the file:// protocol for local files isn’t supported in the Promoted Links list in SharePoint Online. The http:// or https:// protocols are supported in the Promoted Links list.
