Microsoft 365 Family OneDrive Storage Reduced: 6TB Drops to 2TB Shared

Starting October 8, 2026, new Microsoft 365 Family and Premium subscriptions that are new, upgraded, or repurchased after expiring no longer come with 1TB of OneDrive storage per person. They get a single 2TB pool shared by up to six people, which cuts a full household’s total from 6TB to 2TB. Existing subscribers keep the old per-person model until their first renewal on or after May 2, 2027, or sooner if they upgrade their plan, according to Microsoft’s main transition page (Microsoft Support, retrieved October 9, 2026).

What Happened

Microsoft has changed how OneDrive storage works on its consumer Microsoft 365 plans. The old Family model gave each of up to six members their own 1TB of OneDrive storage, for a household maximum of 6TB. Premium and Pro used the same 1TB-per-person model. The new model gives Microsoft 365 Family and Premium subscribers one 2TB pool that every member shares, and Microsoft 365 Pro gets a 5TB shared pool, so a full Pro household loses up to 1TB (Microsoft storage quotas; Microsoft storage FAQs, both retrieved October 9, 2026).

Windows Central and The Register both reported the change on October 9, 2026. Windows Central reports that the plans cost the same as before. Microsoft’s support pages we reviewed don’t mention pricing, so check what you pay in your own account and market.

Here’s the timeline Microsoft’s documentation gives:

• New subscribers: The 2TB shared quota applies to new, upgraded, and repurchased Family and Premium subscriptions starting October 8, 2026.
• Existing subscribers: Your current, larger allocation stays until your first renewal on or after May 2, 2027. That’s the date on Microsoft’s main Changes to Microsoft 365 storage page and in its storage FAQ. One exception: the quota table on Microsoft’s storage quotas page lists April 1, 2027 for existing Family and Premium renewals (Microsoft storage FAQs; Microsoft storage FAQs, Office version; Microsoft storage quotas, retrieved October 10, 2026).
• Upgrading early: If you’re an existing subscriber and upgrade your plan before May 2, 2027, Microsoft says your subscription moves to the shared storage model at that point, not at your next renewal (Microsoft storage FAQs).
• Existing Pro subscribers: The quotas page says existing Pro subscriptions switch to 5TB shared on November 1, 2027.
• Bonus storage: Microsoft says some existing Family and Premium customers who meet eligibility requirements in supported markets might receive temporary bonus storage at renewal, at no extra cost. So your exact outcome may differ from the 2TB headline.

Microsoft also says each member’s files, folders, and mailbox stay private, even though the storage quota is now shared (Changes to Microsoft 365 storage). Your kids won’t see your files. You’ll just be drawing from the same pool.

This is a change to what your subscription includes, set on Microsoft’s side. It is not a bug, a sync glitch, or an outage, so troubleshooting OneDrive or Office on your PC won’t bring the old allocation back.

Who This Affects

The change covers OneDrive cloud storage on these consumer plans:

• Microsoft 365 Family: Moves from up to 1TB per person (6TB max) to 2TB shared.
• Microsoft 365 Premium: Moves from up to 1TB per person (6TB max) to the same 2TB shared pool as Family.
• Microsoft 365 Pro: Moves from up to 1TB per person (6TB max) to 5TB shared.

It doesn’t touch your PC’s local drive. Files you’ve set to stay on your device in File Explorer or Finder still take up local disk space as before. The quota only governs what’s stored in OneDrive’s cloud.

The households that will feel it most are the ones that used the old per-person model as designed. Five or six people each keeping a large photo and video library in OneDrive could easily add up to more than 2TB together. A couple or a small family that never got close to 6TB may not notice. With a shared pool, unused space from one member is available to another, which can be more flexible than six separate 1TB buckets.

How It Stacks Up

Here’s the before-and-after, using only figures from Microsoft’s documentation and the October 9 reporting.

Plan	Previous OneDrive allocation	New OneDrive allocation	Max with paid add-ons	Source
Microsoft 365 Family	Up to 1TB per person, up to 6 people (6TB total)	2TB shared across up to 6 people	Up to 10TB combined	Microsoft storage quotas
Microsoft 365 Premium	Up to 1TB per person, up to 6 people (6TB total)	2TB shared	Up to 10TB combined	Microsoft storage FAQs
Microsoft 365 Pro	Up to 1TB per person, up to 6 people (6TB total)	5TB shared	Up to 10TB combined	Microsoft storage FAQs

Microsoft’s support pages don’t list prices, but Windows Central reports the plans cost the same as before. If that holds in your market, a full six-person Family household loses up to 4TB of included storage without paying any less.

Your realistic alternatives

• Buy more OneDrive storage inside Microsoft 365. Microsoft’s storage FAQ says only the subscription account holder can extend storage, up to a combined 10TB, and add-on storage goes into the shared pool for every member. That’s the least disruptive option because nobody has to move files or learn a new app.
• Switch to the Pro tier. Pro’s 5TB shared pool is the closest match to the old 6TB household total. Microsoft explains how to change plans on its Switch between Microsoft 365 subscriptions page. We couldn’t find a published Pro price in the sources, so check the cost in your account before you switch.
• Move bulk media off the cloud. An external hard drive, a portable SSD, or a home NAS can hold large photo and video archives that don’t need to sync everywhere. That frees up the shared 2TB pool for the files that do.
• Google One, Google Workspace, or Dropbox. These offer family or shared storage, but we found no verified side-by-side comparison against Microsoft 365’s Office apps plus the old 6TB allowance. If you switch storage providers, you may still need Microsoft 365 for Word, Excel, and Outlook.

What Happens If Your Household Goes Over 2TB

Your files aren’t wiped at the moment your plan renews, but going over quota has real consequences. Microsoft’s general over-quota rules say OneDrive stops uploading, editing, and syncing new files, your existing files become read-only, and you can’t send or receive Outlook.com email until usage drops below the limit or more storage is added (Microsoft storage quotas).

For households moving to shared storage, the transition-specific guidance is the one that speaks to your situation: the Changes to Microsoft 365 storage page says that if your subscription exceeds the new limit after the change, you can continue to access your files for up to one year while you manage your storage (Changes to Microsoft 365 storage). Separately, Microsoft’s standing quotas page, which covers over-quota accounts in general, says an account that stays over its OneDrive limit is frozen after three months, and that after six months Microsoft might delete the OneDrive and all files in it (Microsoft storage quotas). Microsoft doesn’t explain how the two policies interact during the transition year.

Don’t count on the one-year window. Get under 2TB, or add storage, before your renewal.

Can You Keep the Old 6TB?

Not under the new model. The sources describe existing subscribers keeping their larger allocation only until their first renewal after the transition date. Nothing we found says renewing early, or having prepaid for multiple years, locks in the 6TB permanently. Don’t assume it does.

There’s also no indication in Microsoft’s documentation that this change is temporary or will be reversed. Treat it as permanent unless Microsoft says otherwise.

What to Do Next

Here’s the one step that matters now: find out how much your household actually stores, and compare that with your renewal date. If the total is well under 2TB, you can relax. If it’s close to 2TB or above it, you have until your 2027 renewal to trim files, add storage, or change plans.

Each member can check their own usage from any of the platforms below. Microsoft’s storage quota covers OneDrive files and email attachments, so check the Microsoft storage page on the web for the fullest view. The desktop apps below show the account you’re signed in with, and depending on the app version and when your plan switches, they may not show the household’s shared total. Treat the web page as the authoritative number. Menu labels can vary slightly between OneDrive app versions.

Windows

• Click the OneDrive cloud icon in the system tray. If you don’t see it, search for OneDrive in the Start menu.
• Click the gear icon, then select Settings.
• Open the Account section to see how much storage is in use against your current quota.

macOS

• Click the OneDrive cloud icon in the menu bar.
• Click the gear icon, then select Preferences (labeled Settings in newer versions).
• Open the Account tab to see your current storage use against your plan’s quota.

Web

• Sign in to your Microsoft account in a browser.
• Go to the Microsoft storage page in your account to see how storage is used across OneDrive and Outlook.
• While signed in, open Services & subscriptions to confirm your plan type and your exact renewal date.

Write down the renewal date. It’s the real deadline for your household. If you renew in spring 2027, give yourself a buffer by finishing cleanup before April 1, 2027, the earlier date in Microsoft’s quota table. If you plan to upgrade your plan before then, do the cleanup first, because an upgrade moves you to shared storage right away.

The Reaction

Early coverage describes a frustrated response. The Register reports that much of the Microsoft365 subreddit was filled with posts complaining about the move, including a top post reminding people to turn off automatic renewal (The Register). Windows Central’s writer says they received several messages from disappointed users (Windows Central). The anger makes sense: according to these reports, pricing stayed the same while a full household lost up to two-thirds of its included storage. Still, for many smaller families, the actual impact will depend on how much they store today.

Our Take

Verdict: Work around it, and don’t panic. Smaller households well under 2TB don’t need to cancel or migrate right away. Existing subscribers keep their current storage until a 2027 renewal unless they upgrade sooner, and nothing is wiped at the moment the quota changes. If you’re already near 2TB, or you’re thinking about upgrading your plan, start planning now.

How worried you should be depends on one number: your household’s total OneDrive usage.

• Under about 1.5TB combined: Low concern. The shared 2TB pool covers you, and it may be more flexible than six fixed 1TB slices.
• Between 1.5TB and 2TB: Moderate concern. Clear out duplicates, old phone backups, and forgotten video folders before renewal so you have room to grow.
• Over 2TB: Real concern. Before renewal, choose between paid add-on storage (up to 10TB combined), the 5TB Pro tier, or moving bulk media to an external hard drive or NAS.

One thing to watch: Microsoft’s main transition page says May 2, 2027, but its quota table still says April 1, 2027. To be safe, plan around the earlier date. Once your plan renews under the new quota, one Microsoft page promises up to a year of file access while you get back under the limit, but its standing over-quota rules make files read-only right away and allow deletion after six months. Treat the renewal date as the deadline.

Wrapping Up

Check your household’s OneDrive usage and your renewal date today. That five-minute check tells you whether this change matters to you. Most small families will be fine on 2TB shared. Large households that relied on 1TB each should decide on add-on storage, Pro, or local storage well before spring 2027 rather than waiting until they’re already over quota.

Step	Action	Applies To
1	Check total OneDrive usage (OneDrive settings or Microsoft account storage page)	All Family/Premium members
2	Note your renewal date in Services & subscriptions	Subscription owner
3	Delete duplicates and old backups, or move bulk media to local storage	Households near or over 2TB
4	Add paid storage (up to 10TB combined) or switch to Pro (5TB shared)	Households that still exceed 2TB
5	Finish changes before April 1, 2027, to cover both stated dates	Existing subscribers
