While examining some elements in the Outlook.com UI to see if I could turn up anything that might shed light on my thread question, I clicked on the "Files" button (paperclip icon) in the lower left corner of the Outlook.com UI, which opened a window titled
"All attachments", which listed one old attachment of mine in the right pane. To my surprise, in the
left pane, there was a "People" menu that when expanded showed some---though
not all---of the people/companies whose addresses were the ones that were showing up as "Suggested contacts" when composing a new message. Huh?! Why are these names, some of whom I never sent/received attachments to/from, in this "Files">"People"
menu? Where are these names being stored?
I should also mention that in the Outlook.com's "People" app (not
the menu item shown in the "Files"/Attachments window that I've referred to above), where the user's contacts would be listed, there are
NO contacts listed.
What in the heck is going on here?
