Outlook provides you with a number of built-in search filters. To use the built-in filters, click in the Search box. Based on your preference, you can use Advanced Search by clicking the filter button on the right side of the search box. Alternatively, the Outlook ribbon will change to show the Search tab and you use any of the options in the Refine group to refine your search results.
You can find the search box at the top of the screen whether you are using the Simplified Ribbon or the Classic Ribbon.
