Sometimes the hyperlinks in a document lose the blue font and the underlining – the hyperlink still works but it’s difficult to tell it is there. The method for bringing back the blue font and the underlining is in Rhonda’s excellent newsletter https://cybertext.wordpress.com/about/ which always has fantastic Word tips. This one she got from Suzanne S Barnhill, as explained here: https://answers.microsoft.com/en-us/msoffice/forum/msoffice_word-mso_other-mso_2010/making-links-in-word-blue/bf5d471d-4a5f-4037-8e42-372de429864f
1. Display field codes using Alt+F9 (or Alt+Fn+F9). This will make your hyperlinks display as field code so wordpress.com/home/southampton-exam-factory.com will change to { HYPERLINK “https://wordpress.com/home/southampton-exam-factory.com” }
2. Press Ctrl+H to open the Replace dialog.
3. Click More to expand the dialog.
4. In the ‘Find what’ box, type ^d HYPERLINK. ^d represents any field code, and therefore ^d HYPERLINK looks for a HYPERLINK field code.
5. With the insertion point in the (empty) ‘Replace with’ box, click Format, then Style.
6. Select the Hyperlink style (it’s a long way down) and click OK.

7. Click Replace All.
8. Press Alt+F9 (or Alt+Fn+F9) again to toggle the field display back to results which has blue underlined hyperlinks.
