If you are using the built-in headings you will see paragraphs indented in Outline view (View tab | Outline view). Heading 1 paragraphs will be displayed at level 1 (no indent), Heading 2 paragraphs will display at level 2 (indented compared to Heading 2), etc. Actually, any paragraph to which you assign an "Outline level" other than "Body Text" will be indented in Outline view. To assign outline levels, use the Paragraph dialog box (you can display the dialog box by right-clicking a text paragraph and choosing Paragraph from the context menu).
If you mean that you always want to display and print indents with numbered paragraphs, specify indents as you set up your outline/multilevel list. For an existing list, place the insertion point in the first level 1 item (the first Heading 1 paragraph of the document assuming that this is a list of headings) and then click Home tab | Multilevel List | Define New Multilevel List.
