How do I create a collapsible section in Outlook?

Select all the headings you want to collapse. Then, on the HOME tab, click the Paragraph dialog box launcher, and check Collapsed by default. Now, when readers open the document, they can use the collapsed headings like a table of contents – choose the section they want to read and click the triangle to expand it.
