Question : Run an Outlook 2007 rule only if the mail is 1 week old

How do I run an Outlook 2007 rule on mail only if it is older than 7 days? I don't want to "specify a date span" everytime. The rule simply moves the mail into a subfolder.

Answer : Run an Outlook 2007 rule only if the mail is 1 week old
