Want to seem like you are ALWAYS up on reading your email? Want to impress people and get that read receipt back to them within seconds of your receiving their message?
Create the following filter in outlook:
Apply this rule after the message arrives
where my name is in the To or Cc box
mark it as read
Your perceived productivity will skyrocket!
(Note: I am NOT suggesting that anybody actually do this! For one thing, everyone will wonder why you have read all of their messages and not responded to any of them…)
