For years I've used the desktop Outlook, along with our ISP, to store all contacts. The last few years I've begun to use the People app in Windows 10, because as I understand it, the People app is more associated with Office 365. But the one thing that is really very irritating, is I've no idea at all where the contact is stored. Since I've got years worth of contacts from the old ISP/.PST file, or in the People app used by Outlook.com, I don't know where anything is, until I try to edit it. It's VERY FRUSTRATING to get the, "You can't edit it here, but you can add to it here." How about telling me where in heck it is, so I can either edit it there or delete it and put it all into the People app where I can use it either using Office 365/Outlook/Outlook.com, PLEASE!!
