Security 2017 continues to ID incoming emails as spam

Hi,

Am running Windows 10 - Outlook 2010 and Norton Security 2017.

Settings: 

ALL UPDATES - current.

Outlook - NO automatic filtering

Norton Security - Antispam OFF

But...I am still having emails directed to Outlook's "Spam" folder.  Which is inconvenient, to say the least.

Any solution that I'm not aware of....or is this simply a bug of some sort?

Thanks!

John
