If you're an Office 365 Home subscriber, did you know you can share your subscription with up to four other members of your household? Each person can install the Office apps on their own PC or Mac, tablet, and phone, and everyone gets their own 1 TB of storage and 60 Skype minutes a month.
Not a Home subscriber? It's easy to switch from Office 365 Personal to Home, so you can share the Office apps and services with your loved ones.
