Upon saving my Excel sheet, I receive the following error message:

We found a problem with one or more formula references in this worksheet.

Check that the cell references, range names, defined names and links to other workbooks in your formulas are all correct.

“Error Checking” (under “Formulas” → “Formula editing”) returns

The error check is completed for the entire sheet.

What is the fastest way to find what is causing this problem?

Excel in Office 365 ProPlus, Windows 7.
