Use Outlook to turn messages into items you can act on.
When you read a message in e-mail, that message often causes you to take some sort of action. Your action might be to respond right away with a reply, or to take some secondary action, such as setting up a meeting.
In order to clear away the clutter in your Inbox, think about a message as you read it and decide whether it requires action. If action is required, think about what you need to do. Should you respond right now? Later? Do you need to flag the message for follow-up, or create a task? Use Outlook to take action when and how you need to.
