The formatting settings will apply once you’ve enforced the change. Once you’re happy with the formatting options selected, press OK to save the settings. Alternatively, press None or All to select or uncheck all items. If you want to use Word’s recommended minimum option (with only basic styles available), press Recommended Minimum. In the menu, select the styles you wish to allow on your document. To limit certain formatting styles from use, select the Limit formatting to a selection of styles checkbox, then press the Settings option underneath. From the ribbon bar, press Review > Restrict Editing. If you want to allow changes to your Word document, but restrict the type of formatting that can be used (for instance, to maintain a set style), you can do this using the Restrict Editing menu. Restrict Word Document Editing by Formatting Style To protect parts of a Word document from editing, here’s what you’ll need to do. If you’re part of a Windows domain, you can also use the Rights Management Service (RMS) to restrict document editing, based on your user account. You can restrict changes by limiting the available formatting options or by restricting the areas that can be edited. Thankfully, Microsoft Word includes additional controls that allow you to protect parts of a Word document from editing. Doing this, however, restricts any changes to the document as a whole.
