My exchange account has lots of folders under the inbox, helps deal with the volume of different people/sections I deal with.

Now what I would love to be able to do is have mail (which is moved to those sub folders by rules) show in a single folder as happens with the Outlook Unread Mail Search folder. It is a pain not to have a new mail indicator (even though you hear the received mail sound) and a common place like the unread search folder to preview it. Takes a lot of nuisance value to scroll through both my mail accounts sub folders and find the one which has the new mail in it
