I have a rule that makes a copy of all sent email. Normally works fine. However, if I include a shortcut as an attachment I get a Rules in Error that reads "Cannot copy to the 'Sent Items' folder" where Sent Items is a folder under Personal Folders in the pst. To reactivate the rule I go to Rules Wizard and re-check the rules box - until the next time I try to email a shortcut attachment. Problem is repeatable. Something unique about a shortcut as an attachment that is different from a file as an attachment when it comes to the copy in the rule.
