You can share your Office 365 Home subscription with up to five people in your family. Everyone gets their own Office apps to install on all their devices, plus 1 TB of OneDrive cloud storage each, and other services.
The easiest way to do this is to set up your Microsoft family group. Once the members are added, Office is automatically shared with them, and you get other benefits such as features to keep your family safe online, and connected even when you're apart.
Go to your Microsoft account page and select Create a family group.
Sign in with the same Microsoft account that you used to set up your Office 365 Home subscription.
Enter the appropriate information for the family member that you want to invite, and send the invitation.
Note: If your family member doesn't have a Microsoft account, you can create one for them on the Add a family member window.
Office will be automatically shared with your family members after they accept your invitation. They can then go to their Microsoft account and install the Office apps.
Note: You can add more members after sending the first invite, or if you want to invite others later, go back to your Microsoft account page and select Add a family member.
Not a Home subscriber? It's easy to switch to a different Office 365 for home subscription, so you can share the Office apps and services with your loved ones.
