If you're anything like me, you have a huge problem both prioritizing incoming email and getting work done with a perminant inflow of email into your inbox that requires attention.
If this sounds like you, check out Email Prioritizer, a concept project from Microsoft Office Labs:
Email Prioritizer is a plug-in for Outlook that helps you manage email overload. It gives you the ability to temporarily pause new email arrival by clicking its “do not disturb” button and prioritize email with a 0-3 star rating system. This add-in simply adds two buttons to your toolbar, but the power is in how it can simplify your email life.
