    To look at a sample of the available templates, simply click Format  -> Templates. Then expand the category you're interested in and begin clicking through the templates you'd like to view. When you click on a template, OneNote will actually create a new page, then apply the template to it, unless you're already starting with a new page.

    Tips:

    • There is no preview of templates. To see what a template looks like, follow the instructions in the paragraph above.
    • To set a template as the default for a given section, just navigate to the section, then right-click the template and select Set as Default for This Section.
    • To customize your own template, just set the page up exactly as you want your template to look, then click Save current page as a template at the bottom of the Templates task pane. You will then be prompted to enter a template name and specify whether you want the template to be used as a default template for the current section.
      • Your new customized template will appear in a new category called My Templates.
    • To delete a customized template, right-click the template -> Delete.
      • Only customized templates can be deleted.

    Notes:

    • Templates cannot be able to applied an existing page, unless it's never had any content on it before.
    • Templates can only be applied to a single page at a time, i.e. they cannot be applied to an entire section or notebook.
    • A while ago I created a powertoy called OneNote Template Manager to circumvent the 2 points listed above. With it, you can apply a template to pages that you have already added notes to. In addition, you can create your own custom templates and apply them to any scope you specify, i.e. apply a template to a range of selected pages, or to an entire section or notebook, etc. However, the templates created with this powertoy are not able to be managed inside of OneNote, but rather inside the powertoy itself.
