Microsoft 365 Family Storage Cut: What a Shared 2 TB Pool Means

By Jaspal Singh October 10, 2026 Updated: October 10, 2026

Microsoft is replacing the 1 TB-per-person OneDrive allowance in Microsoft 365 Family and Premium with a single 2 TB pool shared by up to six people. New subscribers got the shared model on October 8, 2026; existing subscribers switch at their first renewal on or after May 2, 2027. Solo users gain space, but households of three or more lose it.

What Happened

Microsoft published a support page titled "Changes to Microsoft 365 storage" that rewrites how cloud space works in its consumer subscriptions. Until now, Microsoft 365 Family and Premium gave each of up to six members their own 1 TB of OneDrive storage, so a fully shared plan carried 6 TB in total. Under the new model, those plans include 2 TB of storage that the primary subscriber and up to five additional members all draw from. Microsoft 365 Pro moves to a 5 TB shared pool.

The single-user plans do not change. Microsoft 365 Basic stays at 100 GB and Microsoft 365 Personal stays at 1 TB, both reserved for the account holder alone.

The timing has two tracks. According to Microsoft's page, new and upgraded subscriptions moved to shared storage on October 8, 2026. Existing Family and Premium subscribers keep per-person storage until their first renewal on or after May 2, 2027, and Microsoft says they will get an email before that renewal. A subscriber who upgrades before May 2, 2027 (for example from Family to Premium) moves to the shared model at that point. One who downgrades keeps the current model until a renewal on or after that date.

Prices are not changing alongside the storage. PCWorld lists Microsoft 365 Family at $12.99 a month or $129.99 a year and Premium at $19.99 a month or $199.99 a year in the US, the same as before. The Register, which first highlighted the change on October 9, worked out the headline number: a household using all six seats can lose up to 4 TB of combined storage, and Pro households up to 1 TB. Tom's Hardware, PCWorld, Android Authority and TechRadar followed the same day, with several reporting subscribers on Reddit threatening to cancel.

Why It Matters

Microsoft 365 Family has long been one of the cheapest ways to get a lot of cloud storage. At $129.99 a year for up to 6 TB, it worked out to roughly $22 per terabyte per year, which is why many households bought it as much for OneDrive as for Word and Excel. Cutting the pool to 2 TB at the same price triples the effective cost per terabyte for a full household.

Who wins and who loses depends almost entirely on how many people share the plan:

One person on Family or Premium: storage doubles from 1 TB to 2 TB, since the owner can use the whole pool if nobody else is added.
Two people: total storage stays at 2 TB, but it is no longer split 1 TB each. One heavy user can now take more than half.
Three to six people: total storage falls from 3–6 TB to 2 TB. A six-member plan loses two-thirds of its capacity.

The change also alters how members relate to one another. Before, one person filling their 1 TB had no effect on anyone else. In a pool, the first person to run a phone's full-resolution photo backup can stop uploads for everyone. The Register gives an example: four members using 500 GB each fill a Family plan completely, and nobody can upload another file.

It is not the first time Microsoft has walked back OneDrive storage. The Register points out that the company dropped its unlimited OneDrive offer for Office 365 consumers in 2015, a year after introducing it, and has trimmed other allowances since. For families who chose Microsoft 365 as their photo archive, this is another reminder that cloud quotas are terms of service, not property.

How It Works

Microsoft's support page describes the mechanics in a few rules. The primary subscriber and up to five additional members share one storage quota. Shared storage changes how space is allocated, not who can see files: each person's documents and photos stay private unless they share them. Storage add-ons bought by any member go into the shared pool rather than to that person, and Microsoft says a pool can be expanded to as much as 10 TB this way. Eligible free storage grants that individual family members already hold also contribute to the pool.

What counts against the pool is the same Microsoft account storage people already know: OneDrive files and, for Outlook.com users, email and attachments have counted toward Microsoft cloud storage for years. The new page does not list the services separately, so it is worth checking the storage dashboard at account.microsoft.com, which Microsoft says shows usage for the subscription, before your renewal date.

When a household approaches the limit, Microsoft says members get notifications as the subscription nears 2 TB. If the pool is exceeded, files are not cut off right away: Microsoft states they "remain accessible for up to one year" while the household brings usage down. In practice that means existing files can still be opened and downloaded, but new uploads will stop syncing once the pool is full. After that grace year, the page does not say exactly what happens to data still over quota.

To soften the switch, Microsoft says existing Family and Premium customers in eligible markets may receive transitional bonus storage at renewal, at no extra charge. It does not say how much, how long it lasts, or which markets qualify.

Microsoft's own explanation is flexibility. Its FAQ says a shared pool "helps ensure that one person doesn't run out of space while other members have unused storage available." Asked on the same page whether this is a reduction, Microsoft notes that total storage varies by plan and that the shared model lets members who need more use more. Tom's Hardware framed the cut against industry-wide storage supply shortages, but Microsoft's page does not mention cost or supply as a reason.

If you want to plan ahead, the arithmetic is simple. Add up each member's current usage from the storage dashboard. If the total is under 2 TB, nothing practical changes yet beyond the risk of one person crowding out others. If it is over 2 TB, the options are to buy add-on storage for the pool, move one or more heavy users to their own Microsoft 365 Personal plan (1 TB dedicated, about $99.99 a year), move photos or video to another service, or cancel. Microsoft's page explains that cancelling at account.microsoft.com/services/microsoft365 keeps benefits running to the end of the paid period.

What's Still Unknown

Several details that matter to heavy users are missing from Microsoft's page. It does not say how big the transitional bonus storage is or how long it lasts. It does not give a renewal date for existing Microsoft 365 Pro subscribers, only for Family and Premium. It does not explain what happens to files that remain over quota after the one-year grace period: whether they become read-only, get deleted, or simply stay frozen.

Pricing for storage add-ons under the new pool has not been spelled out in the support page either, and it is unclear whether Microsoft will adjust plan prices in markets where Family is sold heavily discounted through retailers. Microsoft also has not said whether it will revise the change in response to subscriber pushback, as it partially did after the 2015 unlimited-storage reversal, when existing users were offered a year of extra space.

Frequently Asked Questions

When does the Microsoft 365 storage change affect me?

It depends on when you subscribed. New and upgraded Family, Premium and Pro subscriptions moved to shared storage on October 8, 2026. If you already pay for Family or Premium, nothing changes until your first renewal on or after May 2, 2027. Microsoft says it will email you before that renewal, and upgrading your plan earlier moves you to the shared model at the time of the upgrade.

How much storage does Microsoft 365 Family include now?

Microsoft 365 Family and Premium now include 2 TB of OneDrive storage shared by the owner and up to five other members. Previously each of the six members had a separate 1 TB, for up to 6 TB in total. Microsoft 365 Pro now has a 5 TB shared pool. Personal stays at 1 TB and Basic at 100 GB, both for one person only.

Can other family members see my files in the shared pool?

No. Microsoft says the shared model changes only how storage space is allocated, not who can access files. Each member's documents, photos and other files stay private by default, exactly as they did before, unless that person chooses to share them. The only thing members share is the quota, so one person's large uploads reduce the space left for everyone else on the plan.

What happens if my family goes over the 2 TB limit?

Microsoft says members get notifications as the subscription approaches its 2 TB limit. If the pool is exceeded, files remain accessible for up to one year while the household reduces usage or adds storage. New uploads will not sync while the pool is full. Microsoft has not explained what happens to files still over quota after that year, so trimming usage before renewal is the safer approach.

Is Microsoft lowering the price of Microsoft 365 Family?

No. Prices are unchanged with the storage cut. In the US, PCWorld lists Family at $12.99 a month or $129.99 a year and Premium at $19.99 a month or $199.99 a year. Microsoft says some existing customers in eligible markets may receive temporary bonus storage at renewal at no charge, but it has not published the amount or how long it lasts.

Can I buy more storage for the shared pool?

Yes. Microsoft says storage add-ons purchased by any member are added to the shared pool rather than to that person's own use, and a pool can grow to as much as 10 TB this way. Eligible free storage grants that a member already holds also count toward the pool. Microsoft has not yet detailed add-on pricing on its storage changes page.

Should a heavy OneDrive user switch to Microsoft 365 Personal?

It can make sense. Microsoft 365 Personal includes 1 TB reserved for one person, so a member using close to 1 TB can move to Personal and leave the full 2 TB family pool for others. The trade-off is paying for a second subscription. Check each member's usage in the Microsoft account storage dashboard before deciding, ideally well before your May 2027 renewal.
