I didn't see anything that said anything about emails in the risk log.
I see the following for Status:
1) Antivirus and Antispyware Protection
2) Proactive Threat Protection
3) Network Threat Protection
Each has a 'Options' button but nothing in here has 'Risk' as an option.
I see the following for View logs:
1) Antivirus and Antispyware Protection
-Scan Log
-Risk Log
-System Log
2) Proactive Threat Protection
-Threat Log
-System Log
3) Network Threat Protection
-Traffic Log
-Packet Log
4) Client Management
-Control Log
-Security Log
-System Log
-Tamper Protection Log
Any other thoughts on where this may be logged?
