Stuck using Outlook at work? How to get to Inbox Zero with Outlook's built-in tools:
The other thing we need to do is create a place to move your inbox item to. I don't try to organize my email into different folders, my preference has been to put all my mail (once I've acted on it) into a monthly folder. I do this mostly to manage the size of my mail file on our LAN. Doing this means all my rules can use the same folder and I don't need to remember where to put email. The folder I've set up is called 0-current month, having the leading zero puts the folder at the top of the alphabetical ordered list in Outlook.
