Why Do you need a custom 404 page in SharePoint?

You will need the following to complete this tutorial

  1. Site collection admin access in the SharePoint site
  2. SharePoint Designer 2013

If you have both of the above then follow the below steps to create your custom page not found page in SharePoint.


#1. Create a new SharePoint page and customize it as you want

The first step for creating a custom 404 page is to have a SharePoint page ready for the same purpose. So, create a new SharePoint page and customize it.
To keep this tutorial simple, I have not shown how to add custom JavaScript to read the URL and give a corresponding response.

As mentioned above I have created a simple page(image below) and named it as Page Not Found(you can name it as you wish). As you can see I have customized it with some basic images and texts.
After creating the page, copy the link from the navigation bar as below

#2. Connect To Site from SP designer

Now connect and open the SharePoint site in SharePoint designer

Connect to SP designer newbietechie

#3. Open the Site Options and Modify it

After connecting to the site using SharePoint designer, open the site options pane from the top menu. Then check if the below parameter exists, if it exists then your site already has a 404 error page configured. On the other hand, if the parameter doesn’t exist then add a new parameter and set the value as the site link of the page you copied in first step. Follow the images below to understand better.
Parameter name: vti_filenotfoundpage
Value: /sites/TestSite/SitePages/PageNotFoundError.aspx
note: for you the value might be different as it depends on the page link
