Error! Reference source not found is an error notification that displays when the end user attempts to update a field that contains an invalid or broken link.

Many end user’s encounter an unusual situation where, all the reference fields suddenly disappear displaying the Error! Reference source not found message when they attempt to print a document.

This error message occurs on Microsoft Word, but is not exclusive to any specific version of Microsoft Office (2010, 2013, and 2016) or Windows (7, 8.1, and 10).

User error is primarily to blame for this issue. As oftentimes, users may remove a specific item caption or section of their content (i.e. tables, figures) that is being referenced somewhere else in the document. Ordinarily this wouldn’t be an issue, only that the user forgets to alter the reference field.

However, that isn’t the only reason why this error may occur. So let’s take a look at that.

What Causes Error! Reference source not found?

I went through a series of sites, looking at various user experiences, along with workable solutions, and found a number of commonalities. Based on that study, I can say, categorically, that the main causes of this error, is as follows:

  • Microsoft Office installation is corrupted: Many users report that the Error! Reference source not found was as a result of corruption. In this particular scenario, the error occurs, even when the cross-reference field should work.
  • The bookmark cross-referenced was removed: In the vast majority of situations, this error message is the result of a deleted cross-referenced bookmark. In situations like this, several steps, within the Microsoft Word app, must be taken. We’ll delve deeper into that, later on in this tutorial.

In addition to that, you also have to consider virus infections, OS corruption, etc. General culprits, for a great many potential woes.

Now, with that out of the way, let’s take a look at the various solutions you can adopt today.
