If you subscribe to Microsoft 365, you'll be prompted to sign in to use Office after installation, or after you sign out. Your subscription has a sign-in limit that determines how many Office installs you can sign in to at the same time. Use the tabs below to select your subscription type and learn more about sign-in limits for your subscription.
With Microsoft 365, you can install Office on all your devices and sign in to Office on five devices at the same time. This includes any combination of PCs, Macs, tablets, and phones.
Here are some tips for using Microsoft 365 on multiple devices:
•Each person who uses Office on a device must have an account that's associated with Microsoft 365. This can be the account that subscribes to Microsoft 365, or any accounts that share a Microsoft 365 Family subscription.
•When you install Office on a device, you'll be prompted to sign in the first time you start an Office app.
•Office remains activated as long as you're signed in. If you sign out, your account’s license is removed and the app is deactivated. You can view and print files, but not create or edit files.
To activate Office after you've signed out, you can sign in again with the account that’s associated with your subscription.
•If you have more than five devices, Office will sign you out of devices automatically to stay within your sign-in limit. To use Office on a device where you've been signed out, just sign back in.
I signed in. Should I stay signed in?
We recommend staying signed in to Office so that your apps remain activated.
What happens if I sign out of Office?
If you sign out, your apps will be deactivated. You can view and print files, but not create or edit files, until you sign back in. To learn more, see What happens when you sign out of Office.
If I share Microsoft 365 Family, how does signing in work?
You can share your Microsoft 365 Family subscription with up to five other people. Each person will use their own Microsoft account to install Office on all their devices and be signed in to five at the same time.
Microsoft 365 includes everything you know in Office 365. Microsoft 365 is designed to help people and businesses achieve more with innovative apps, intelligent cloud services, and world-class security.
