I just installed NIS v22.5.4.24 on Windows 10 with Office 365. All products are fully patched. The anti-spam addin for Outlook is not showing up in Outlook. I did a support session with a Norton support guy. He uninstalled NIS and reinstalled it and it still doesn't work. All other NIS functions seem to work, just not Anti-Spam. I really need this to work, any help would be appreciated.
