NIS2011 Outlook plugin not working with favorite folder

I have a favorite folder for my unread email in my inbox.  The Norton Antispam Outlook plugin works with my inbox folder but is not working with my unread email folder. 

I have tried unchecking and checking with Antispam Client integration.  Didn't help. 

I reset the default data file for my Outlook profile.  Didn't help. 

I have Outlook 2003.  What else can I try?
