Microsoft targets Dropbox and Google with unlimited OneDrive storage for Office 365 subscribers
Microsoft is removing its OneDrive storage limits for Office 365 subscribers. If you're an Office 365 Home, Personal, or University subscriber then OneDrive storage will be unlimited …
Context & Ripple Effects
This is the peak of a storage escalation Microsoft began in June 2014, when it raised free OneDrive to 15GB and bundled 1TB into Office 365 ([[a:1204873]]); weeks later Google countered with Drive for Work's unlimited $10-a-month tier ([[a:1204931]]). By stripping all caps for Office 365 Home, Personal, and University subscribers, Microsoft turns storage from a product into a perk of the Office subscription, aimed squarely at Dropbox and Google.
The pickup was broad — TechCrunch, ZDNet, GeekWire and the Android-focused outlets all carried it — reflecting how directly this hit the consumer-cloud race. But the arc bends back fast: within a year Microsoft walked the promise back entirely ([[a:835577]]), which makes today's announcement less a new equilibrium than the high-water mark of the storage arms race.
First-order effects
- Dropbox's core paid pitch — more gigabytes — is undercut overnight, since unlimited storage now ships inside an Office 365 subscription many households already pay for.
- Existing Office 365 Home, Personal, and University subscribers gain effectively uncapped OneDrive at no extra cost, resetting what 'included' means in a productivity subscription.
Second-order effects
- Google, already committed to unlimited storage for business customers via Drive for Work, faces pressure to extend or defend unlimited positioning on the consumer side of Drive rather than cede the framing to Microsoft.
- Standalone storage vendors like Dropbox are pushed to compete on sync quality, collaboration, and workflow integration instead of raw capacity, because capacity pricing has collapsed to zero at the top end.
Third-order effects
- The 2015 reversal ([[a:835577]]) showed unlimited storage was economically untenable at scale, pushing the industry toward storage-as-lock-in: by 2018 Microsoft was giving OneDrive away free to businesses mid-contract with Google, Box, and Dropbox ([[a:926468]]), treating storage purely as a switching-cost weapon.
- If the pattern holds, cloud storage stops being priced on volume altogether and becomes a bundle feature of per-seat productivity suites — the logic behind later moves like 365 Basic replacing the standalone 100GB plan.
The trend: Cloud storage is shifting from a metered standalone product to a bundled retention weapon in the Microsoft-versus-Google suite war — a race whose own endpoint, unlimited, proved unsustainable within a year.
