@ankit shuklaHmmm. OK, I'll take your word for it, but I still don't understand how the Windows 10 People app, which I have connected to my Outlook.com account/contacts; and the Outlook.com People have differences. What is the cause of those differences?
I'm with you. I can't see any of the outlook products being synced as far as contacts/people/or whatever name you give it in the product your in. My wife has totally disappeared from my contacts but I can still email her. What a mess!
