So, I start to type a name in the sender, and Outlook inserts who it thinks I mean as I'm typing. The problem is, it's inserting emails that are NOT in my contacts list.
I deleted the image cache, but it's still grabbing unknown emails from somewhere. Where?

MacOSX 10.12.5 (Sierra)
Outlook for Mac 2016, 15.11.2

Thanx
Em
