You can use different headers and footers on different pages in your document, so long as the pages use different page styles. Office provides several predefined page styles, such as First page, Left page and Right page, or you can create a custom page style.
You can also use the mirrored page layout if you want to add a header to a page style that has different inner and outer page margins. To apply this option to a page style, choose Format - Page, click the Page tab, and in the Layout settings area, choose “Mirrored” in the Page layout box.
For example, you can use page styles to define different headers for even and odd pages in a document.
