Outlook users can specify the importance of an email message when sending to other Outlook users. This might specifically be for Exchange/Outlook users, I am unsure.
Using Gmail to send a message to an Outlook user (or even another Gmail user) can you specify the importance flag?
If so, how?

Unfortunately that feature is not available in the Gmail interface. This type of thing is what makes me not want to use it as a primary personal service... I ran across the feature request at one point on the support site, but I can't find the exact one now. Here's one from the Google Apps Help Forums.
