Improved document protection
In Microsoft Office Word 2003, document protection can be fine-tuned to control document formatting, content, or both. For example, you can specify that only certain styles are available to use, and those styles cannot be modified. When protecting a document for changes to content, you no longer have to apply the same restriction to everyone and to the entire document. You can selectively allow certain people to edit specified parts of the document.
Restrict formatting
When you restrict the formatting of a document, you prevent users from applying styles that you don't explicitly make available. You also prevent users from applying formatting directly to text, such as bulleted or numbered lists or font characteristics. When formatting is restricted, the commands and keyboard shortcuts for applying formatting directly are unavailable.
Selectively allow editing in restricted content
When you protect a document as read-only or for comments only, you can designate parts of the document to be unrestricted. You can also grant permission for specific individuals to modify the unrestricted parts of the document.
