I don't know if it's the same 'issue' as I had. Under 'Personal' I created what I thought were folders and titled them by date. A few years ago I deleted folders from 2009 to 2012 to get rid of the no longer required old mail. To my surprise if I searched for 2010, for example, in the search box a load of 2010 mail appeared. So the folders are really only labels and had to delete the 2010 mail manually.
