I've been using Microsoft Outlook for many years now. I like to keep all the e-mails I receive, never delete anything (I receive 50-200 e-mails a day). For the purpose of efficiency, what I do is delete (i.e. click the "Delete" button on my keyboard) every e-mail I receive that does not require special treatment or filing. Once a week or so I copy all the "Deleted Items" folder to a big folder I have called "All Non-Filed Mail". If I encounter a spam e-mail or some other mail that "really" requires deletion, I just use Shift-Delete.
I'm well aware of this method's hazards (e.g. the risk of cleaning the folder by mistake), however it's the only single-key operation I know of to remove an e-mail from my Inbox (Ctrl-something is not a single key for this purpose), and I've grown accustomed to it.
I wanted to know if there's any way to configure the operation of the Delete button to send an item to a specific folder?
I currently work in Outlook 2007, but I'm hoping to receive answers that will also be relevant for other versions.
