This Mailbox category displays All mail you have in your mailbox from every category.  If you wish to review all of your mail irrespective of how it has been filed, or read, both incoming and outgoing, you can do that by using the Mailbox category designated All.  This is helpful when you cannot remember how you may have filed mail and you wish to scroll through everything to find something you have lost.  You can view any mail from this Mailbox category,  and you can also click the File button and use a Keyword or Keywords in order to classify that mail more appropriately so that you don't have to resort to scrolling through all of your mail on a future occasion.
