Many of us juggle multiple email accounts between our professional and personal lives. Instead of managing multiple separate address books, you can use Windows 10’s People app to bring together all your contacts into a single, centralized interface.
The People app is a hub for all your contacts. It’s a competent contact manager that can store a wide variety of information about each person, including name, email address, street address, title, phone number, and much more. As with the Mail and Calendar apps, the People app only works with online accounts. You cannot use this app to create and mange contacts that are stored locally in your PC.
