What is the difference between Internet Email Protect and Outlook Email Protect in SEP 14

1. Could you please explain why there is separate option for Outlook and Lotus email protection when all outgoing & incoming emails could be scanned through 'Internet Email Auto-Protect' option? Why has Symantec separated Outlook and Lotus Notes from other email Programs?

2. Does Symantec "Outlook Email Auto-Protect" option scan encrypted emails that are sent on POP3 over SSL? I have read the following article which says that Internet Email Auto-Protect option DOES NOT scan encrypted emails. I want to know if Outlook Auto-protect also behaves the same.
