Question details

The user wants to know how to share a Microsoft 365 Family subscription with a spouse or family member and whether having more than five devices requires additional licenses.

Product: Microsoft 365 Family
Device & OS: not provided
Scenario: Sharing an active Microsoft 365 Family subscription with another person to utilize separate accounts and avoid hitting device limits.
Observed behavior: Currently using the same email address and password across all devices, which counts toward a single user's limit and does not create separate sharing identities.

Before you start

Ensure you have an active Microsoft 365 Family subscription, as the Personal plan cannot be shared, and have your primary Microsoft account credentials ready.

Solution 1Recommended

Share the Subscription via Individual Microsoft Accounts

Invite your family member using their own distinct Microsoft account so they receive their own 5-device limit and private 1 TB of OneDrive storage.

Using the same email address and password on all devices does not provide separate sharing identities and will quickly consume your individual device limit. By properly assigning Family subscription seats to individual accounts, each person can install the apps on up to five devices.

Create a New Account (If Necessary)

If your spouse or family member does not already have a Microsoft account, have them navigate to https://account.microsoft.com and create one for free.

Log into Your Services Dashboard

As the primary subscription holder, go to https://account.microsoft.com/services and log in with your main email address and password.

Send the Sharing Invitation

Locate your Microsoft 365 Family subscription on the dashboard, navigate to the sharing section, and send an invitation to your family member's email address.

Accept and Install

The family member must log into their own email, accept the sharing invitation, and then they can download and install Microsoft 365 on their own devices using their personal credentials.

Sharing Limit: A Microsoft 365 Family subscription can be shared with up to 5 other people, meaning a total of 6 users can benefit from the plan.

Solution 2

Verify Your Subscription Type

Confirm that your current plan supports family sharing before attempting to send invitations.

Frequently Asked Questions

Can I share Microsoft 365 Personal with my family?

No, Microsoft 365 Personal is restricted to a single user. To share your subscription with up to five other people, you must upgrade your plan to Microsoft 365 Family.

How many devices can each shared user install Office on?

Each individual you share your Microsoft 365 Family subscription with can install the Office applications on up to five devices simultaneously.

Does sharing my subscription mean we share OneDrive storage?

No. When you share the subscription using individual Microsoft accounts, each user receives their own private 1 TB of OneDrive storage. Your files remain completely separate and private.

Why shouldn't we just share the same email and password?

Sharing the same login credentials means all devices count against a single user's 5-device limit. It also merges your OneDrive storage, email, and preferences, eliminating personal privacy and data separation.
