I don't know how this happened. I have my gmail account and an outlook account in the win 10 "People." The app has multiple copies of the contacts sometimes more than just 2. I'd like to remove all the contacts and accounts and start fresh. I cant find how to do that. Also removing a single contact requires a one by one removal of linked contacts. I don't know how thy got linked, but I should be able to select them all for removal in one step.

What am I missing?
