You don't have as many editing options when your folder has linked rules. You can either
link to a different rule set or you can break the link completely.
When you select the Manage Rules action for a folder with linked
rules, the Rules page looks like this:
The name and path show you the folder whose rule set is being referenced.
Note: The folder might also inherit rules from a parent folder. A message lets you know if this
is the case.
Changes to the rule set have to be done in the folder where the rules were originally defined. It's easy to get to the Rules page for the source folder: just click View Rule Set.
