Q: I have managed to create a rule that saves the attachment to a disk folder but I also want to move the message to a folder within Outlook. Is this possible using Save Message?
A: You have to add to your rule Move/Copy action which is InboxRULES built-in action. The Move/Copy action should be the last one action in the rule. In your case the rule will contain Save Message action in the first position and then Move/Copy action.
Notice: Move/Copy action is included in InboxRULES for Outlook v2.75 and newer.
