Understand Microsoft 365 Family Sharing and Device Limits

Clarify how subscription sharing works and how many devices each user can install Office on.

Microsoft 365 Family is designed to be shared with up to five additional people (six people total). The limit applies to the number of Microsoft accounts sharing the subscription, not the number of physical devices.

Verify shared accounts

As the primary owner, you can invite up to five other people. Each invited person must sign in using their own unique Microsoft account, ensuring their files and settings remain private.

Install on multiple devices

Every person sharing the subscription (including the owner) can install Microsoft 365 on all their personal devices, such as a desktop, laptop, tablet, and phone. Installing Office on your desktop and your laptop does not count as two shared people.

Manage simultaneous sign-ins

While you can install the apps on numerous devices, each person can only be signed into Office on up to five devices at the same time.

Frequently Asked Questions

Do I have to uninstall Office if I buy my own subscription instead of using a Family invite?

No, you do not need to uninstall the Microsoft Office applications. Simply purchase your new individual subscription and make sure you are signed into the Office apps with the Microsoft account associated with your new purchase. The software will automatically verify your new license.

Does installing Office on my desktop and laptop count as two shared people on the Family plan?

No. The Microsoft 365 Family plan can be shared with up to 6 people (accounts) in total. Each of those people can install Office on all their personal devices without counting against the 6-person sharing limit. However, each person can only be actively signed in on 5 devices at the same time.

How can I pay for my Microsoft 365 subscription using PayPal instead of a credit card?

You can change your payment method by signing into the Microsoft account website. Go to the 'Services & subscriptions' section, locate your Microsoft 365 subscription, click 'Manage', and select 'Change how you pay' to add your PayPal account.
