The most likely reason is that the storage upgrade has not finished applying yet. After buying more OneDrive storage or a subscription, the new quota can take up to 24 hours to appear in the account. If the account is locked, it can take up to 2 hours for the new quota to show, and if it still has not updated after 4 hours, contact support.
What to check now:
- Verify the subscription is visible:
- Go to Manage your storage and check whether the new subscription appears.
- Confirm the correct Microsoft account is signed in:
- If the subscription was redeemed on another account, OneDrive will still show the old quota on the current account.
- In the OneDrive mobile app, tap Me and check the account shown at the top.
- Check the subscription status:
- Open Services & subscriptions in the Microsoft account site and confirm the OneDrive or Microsoft 365 subscription is active.
- Check storage online:
- Sign in and review the Microsoft storage section to see current usage and quota.
- If storage is still full, reduce usage temporarily:
- Delete files or empty the Recycle Bin in Manage your OneDrive storage.
- If either OneDrive or Outlook.com storage is full, mail and file sync can be affected.
What may have been purchased:
- The old standalone OneDrive 100 GB plan has been upgraded to Microsoft 365 Basic.
- Storage plans and pricing vary by country or region, so the exact plan purchased can be checked under Services & subscriptions.
If the upgrade is still not visible after 24 hours, contact support from the billing or storage page.
