When you check your e-mail, are you looking specifically for messages from a particular person?  You can easily find them at a glance by color-coding messages from that individual.

1. Select an e-mail you want to change to a color when it arrives
2. Click Tools on the menu bar
3. Select Organize
   
   
4. Click Using Colors from the Ways to Organize Inbox area
5. Color messages from (their e-mail address will appear here) in (select a color – you have 15 but white is useless as is Silver and Yellow, in my opinion)
6. Click Apply Color
7. Continue with other e-mails and colors, as desired
8. When done, click the X on the far right corner of  Ways to Organize Inbox

Now you can quickly see when e-mail arrives from that individual!
