NIS antispam not working in Outlook 2013

I recently had to reinstall Windows 10 using the "Reset the PC" feature. I was able to successfully reinstall my Outlook 2013 and Norton Internet Security. The Norton tab appears in Outlook and I can flag emails as being spam. There is a Norton antispam folder installed. However it is apparent that nothing is being flagged as spam and nothing is being moved to the spam folder. I've tried the procedure outlined here

where you disable antispam, reboot, and reenable. That doesn't seem to work. I clicked on the register the plug-in link in Norton. No help. At one point I completely uninstalled and reinstalled Norton Internet security. No joy.

Any help is appreciated.
