Check for Unlinked Fields and Recreate the Table of Contents
Verify if the dynamic TOC field was converted to plain text and generate a new Table of Contents to restore update functionality.
When a Table of Contents is selected and 'Ctrl+Shift+F9' is pressed, Word unlinks the field, converting the dynamic elements into static plain text. Once unlinked, the application can no longer recognize it as an updateable Table of Contents, and it cannot be relinked. The best approach is to remove the static text and generate a fresh TOC.
Open the affected document and press 'Alt+F9' on your keyboard. This shortcut toggles the display of field codes across your entire document.
Look at the location of your Table of Contents. You should see a bracketed code similar to '{ TOC \o "1-3" \h \z \u }'. If you only see normal plain text instead of this code, the field has been permanently unlinked.
Highlight the entire plain-text Table of Contents and press the 'Delete' or 'Backspace' key to remove it.
Place your cursor where the TOC should be. Go to the 'References' tab on the top ribbon, click on 'Table of Contents', and select your preferred automatic style to insert a new, dynamic TOC.
Scroll through your document and ensure that your headings are still properly formatted using the built-in styles (Heading 1, Heading 2, etc.) so the new TOC populates correctly.

Frequently Asked Questions
Why did my Table of Contents suddenly turn into normal text?
This usually happens if the Table of Contents was selected and the 'Ctrl+Shift+F9' shortcut was pressed. This specific shortcut unlinks dynamic fields in the document, permanently converting elements like TOCs or cross-references into static plain text.
Can I relink a Table of Contents once it has been unlinked?
No, once a TOC field is converted to plain text, it cannot be relinked or reverted unless you immediately use the Undo function (Ctrl+Z). The only solution is to delete the static text and insert a new Table of Contents from the References tab.
How do I ensure my custom headings appear in the new Table of Contents?
When inserting a new TOC, go to References > Table of Contents > Custom Table of Contents. Click the 'Options' button, and map your custom heading styles to the appropriate TOC outline levels (1, 2, 3, etc.).
Why does Word say 'No table of contents entries found' after I insert a new TOC?
This error occurs when your document text is not formatted with recognizable Heading styles. To fix this, highlight your chapter titles in the document and apply the appropriate Heading styles (like Heading 1 or Heading 2) from the Home tab, then update the TOC.
