How do I create a "sub-folder" of a new list of email addresses (e.g. Block email addresses) under the primary folder "All Address Books”? I can only create a sub-folder under Personal Address Book or Collected Addresses (i.e. a Sub-Sub Folder under the primary folder "All Address Books". I would like to create a new list of email addresses to block emails using “Message Filters” but when I create the rule in the “Filter Rules” window “From” – “is in my address book” – “??????????”, the drop down options are only sub folders of the primary folder "All Address Books “ (i.e. Personal Address Book and Collected Addresses). There is no option to select a sub-folder under “Personal Address Book”. Hence the reason for trying to create a sub-folder under the primary folder "All Address Books". When I select “New List” tab in the “Address Book” window, the 2nd window (called Mailing List) which pops up only gives me options to add a new folder (i.e. Block email addresses) under “Personal Address Book” or “Collected Addresses” not the primary folder "All Address Books”. Any advice would be appreciated.
