Microsoft 365 Family costs $129.99 a year and covers six people. Six accounts, one bill. That gap between the price of one seat and the price of six is what the whole Microsoft 365 sharing market is built on.
Microsoft designed the Family plan to be shared. The risky part lives somewhere else: who ends up holding the subscription.
What the two plans actually are
Microsoft sells two consumer subscriptions. The difference between them is seats.
| Plan | People | Devices at once | OneDrive | Price (Microsoft, Oct 2026) |
|---|---|---|---|---|
| Microsoft 365 Personal | 1 | 5 | 1 TB | $99.99/year |
| Microsoft 365 Family | 1 to 6 | 5 per person | 2 TB shared across the group | $129.99/year |
Both include the desktop versions of Word, Excel, PowerPoint, Outlook and OneNote, plus Microsoft Defender and the mobile apps. Personal comes with one seat. Family comes with six, and that is the whole trick: $129.99 split six ways works out to about $21.67 per person for the year, and everyone keeps a separate Microsoft account.
Storage is the part of this that most guides still describe the old way. Microsoft 365 Family no longer gives each member 1 TB. Since October 8, 2026, a Family subscription comes with 2 TB of pooled storage that all six accounts draw from. Microsoft 365 Personal keeps its own 1 TB, unchanged.
If you already subscribe: the 2 TB pool applies to new and repurchased Family subscriptions from October 8, 2026. Existing subscribers keep their 1 TB per person until the subscription renews on or after May 2, 2027. Source: Microsoft’s subscription sharing support page, checked October 2026. The full breakdown, including the transitional bonus storage and the upgrade catch, is in our news post on the storage change.
How sharing a Family plan works
- One person buys Microsoft 365 Family and redeems the code while signed in with their own Microsoft account. That account becomes the subscription owner.
- The owner opens
account.microsoft.com, finds Microsoft 365 Family under Services & subscriptions, and adds up to five more people by email. - Each invited person accepts the invitation with their own Microsoft account and joins the owner’s Microsoft Family group.
- Everyone installs Office on their own devices and signs in as themselves.
In simpler terms: six people share one bill, not one login. Nobody types anyone else’s password, and the files stay private. Your documents sit in your own account, and the other five people can’t see them unless you share a file on purpose.
Storage is the one exception to the separate-accounts rule. The 2 TB is a single pool that all six of you draw from.
Microsoft’s argument for pooling is flexibility: one person can go past 1 TB as long as the others leave room, which the old per-person model didn’t allow. What’s lost is the ceiling. Six members could previously reach 6 TB between them, and now the household shares 2 TB, so four people sitting at 500 GB each will fill it. If your family already stores more than that, check what’s in OneDrive before you buy. Extra storage can be added to the pool for a monthly fee, up to 10 TB in total.
A few other limits are worth knowing before you plan around this:
- Copilot and the other AI features that come with the subscription belong to the subscription owner only. The other five get the apps, the storage and the security features, but not the owner’s Copilot allowance.
- Each person can be signed in on five devices at a time. Go past that and Microsoft signs out the oldest one to stay inside the limit.
- All six members join the owner’s Microsoft Family group, and an account that’s already in someone else’s family group has to leave it before it can join yours.
The part that decides whether sharing is safe
Sharing splits the group into two roles. The owner holds the subscription. Everyone else is invited into it, and the owner can hand out or take back that access from the Microsoft account dashboard whenever they like.
That asymmetry sits behind most of the stories about people paying for Microsoft 365 and then losing it. Nothing was hacked and no licence was fake. They had paid for a seat inside someone else’s subscription, and the owner stopped sharing.
Third-party sharing services live in that space, and the better ones do keep groups running for years. What you’re buying there is a seat rather than a subscription. That’s fine until the day the reseller changes direction, the seat gets reassigned, or a year passes and nobody renews the arrangement. You’re also paying their cut for the coordination, and the coordination is the part you can replace by filling the seats yourself.
The safe version of sharing looks like this: buy the Family plan, hold it in your own account, and fill the seats with people you’d still know when it renews. Family, roommates, a couple of colleagues. Six people at $21.67 each. Even with just two people, $65 each beats $99.99 each.
Where to buy it
Amazon lists the 12-month Microsoft 365 Family code as an activation code delivered by email. Nothing sits between you and the retailer, and there’s no seat to wait for, because the subscription belongs to whichever Microsoft account redeems the code.
Two things to check before you pay:
- Look at the seller line on the listing. When it says Amazon.com rather than a marketplace seller, returns and support stay simple.
- Make sure the listing is Family and 12 months. Microsoft 365 Personal sits on the same page and costs less per code, and it only covers one person.
Amazon’s price moves with promotions. Microsoft lists Microsoft 365 Family at $129.99/year as of October 2026, so that’s the number to compare against.
Setting it up
Five minutes for the owner, a couple of minutes per guest.
- Buy the code — Microsoft 365 Family on Amazon.
- Redeem it at
microsoft365.com/setupwhile signed in with the account that should own the subscription. Get this step right: the subscription stays with that account, so a temporary email address is a bad choice here. - Install Office from the same account on your own devices.
- Add the other five people from
account.microsoft.com→ Services & subscriptions → Microsoft 365 Family → Share. Enter their email addresses or send them a link. The dashboard shows how many of the five shares are still free, so you always know which seats are taken. - Each guest accepts the invitation with their own Microsoft account, joins your Family group, and installs Office from
account.microsoft.comwhile signed in as themselves.
If you’re the one joining someone else’s plan, that same page shows who you’re sharing with, and you can leave the group yourself if you want out.
Common questions
Q: How much OneDrive storage does each person get? A: Not 1 TB each. Microsoft 365 Family includes 2 TB of pooled storage that all members share, with no cap on any single person inside that pool, meaning one member can go past 1 TB if there’s room. Microsoft 365 Personal still comes with its own 1 TB. Subscriptions that predate October 8, 2026 keep 1 TB per person until the first renewal on or after May 2, 2027.
Q: What happens when the 2 TB pool fills up? A: Uploads stop for whoever hits the wall first. Outlook mail keeps working, because mailboxes aren’t part of the OneDrive pool. The owner can add storage to the pool for a monthly fee, or members can move files elsewhere.
Q: What happens when someone leaves the group? A: The owner can stop sharing at any time, and a guest can leave on their own. Whoever leaves loses the desktop apps and the extra storage. Their files stay in their own OneDrive, but the account drops back to the free 5 GB, so anything above that becomes read-only until they free up space or get another subscription.
Q: If I invite someone six months into the year, do they get a full year? A: No. Sharing covers the time that’s left on the subscription, and the owner’s renewal date doesn’t move for anyone. If you add people mid-term, agree on a split that matches the months remaining.
Q: Can I buy more than one year at once? A: Yes. Redeeming another 12-month code on the same account extends the subscription, up to a maximum of five years. Stacking adds time only, not installs or storage. Codes you haven’t redeemed can sit unused, so buying during a sale and redeeming later works fine.
Q: Is it worth it if I can’t find five other people? A: Two people on a Family plan is already cheaper than two Personal plans, $65 each against $99.99 each. If it ends up being just you, Microsoft 365 Basic is $19.99/year with 100 GB of storage and the web and mobile apps, and Office 2024 is a one-time purchase if you’d rather not subscribe at all.

The short version
- Microsoft 365 Family covers six people for $129.99/year, with the full desktop apps and a 2 TB OneDrive pool that all members share.
- Personal is unchanged at $99.99/year with its own 1 TB, so the Family plan only wins when the seats actually get used.
- Sharing works because each of the six keeps their own Microsoft account. Nobody shares a password, and nobody sees anyone else’s files.
- Account sharing is safe as a mechanism. The risk sits in the ownership: a seat bought inside someone else’s subscription can be taken away.
- Buying the Family code yourself on Amazon comes to about $21.67 per person at six people, and it makes you the owner instead of a guest.
