Grouping allows you to lump together sets of emails based on the criteria you opt to use. By default, messages are grouped by when they are received, i.e. Today, Yesterday, Last Week, Last Month, and Older. Other common criteria include grouping by conversation, importance, and flags.
Sorting dictates the order that emails appear in the specified folder. The default sort order is based on date received, though there are a number of other sorting options available. In addition, you can switch between an ascending and descending sort order.
