How does one set priority on a an outgoing email?
You have the option of normal or important. Important can be set by clicking on the icon.
OK. I saw that (and used it). I was kind of hoping it had something like (low, medium, high, highest) Guess my old email client spoiled me! 
Thanks.
Know what you mean.
However, I did read somewhere that descriptive subject lines were more efficient in conveying priority.
