Check Services & subscriptions first and renew only if the Microsoft 365 subscription associated with this OneDrive account is shown as expired or canceled; an active subscription instead requires account, sharing, and quota-update checks.
1. Check the storage entitlement
- Sign in at https://account.microsoft.com/services using the Microsoft account whose OneDrive dropped to 5 GB.
- Under Services & subscriptions, check the Microsoft 365 status:
- Expired or canceled: renew or repurchase the appropriate subscription.
- Active: do not purchase it again; continue with the checks below.
- No subscription listed: you may be using a different Microsoft account, or the previous storage may have come from someone else’s shared subscription.
When a subscription expires or is canceled, OneDrive returns to the free 5 GB allowance. Existing files initially remain, but uploads, editing, and synchronization can stop when usage exceeds that allowance.[^1^](https://support.microsoft.com/accounts-billing/subscriptions/[Subscription ID] "What happens when your Microsoft 365 subscription expires | Microsoft Support")
2. If the storage came from Microsoft 365 Family sharing
Ask the subscription owner to check whether:
- Their subscription is active.
- Your account is still included in subscription sharing.
- Sharing was removed or the owner left the family group.
Removing someone from sharing reduces that person’s OneDrive quota to 5 GB.[^2^](https://support.microsoft.com/accounts-billing/subscriptions/[Subscription ID] "Stop sharing a Microsoft 365 subscription")
If the owner sends a new invitation:
- Accept it and select Join now.
- Wait up to two hours.
- Open OneDrive Manage storage, refresh the page, and check the quota.[^3^](https://support.microsoft.com/accounts-billing/subscriptions/[Subscription ID] "Troubleshoot sharing a Microsoft 365 subscription")
3. If the subscription is active but OneDrive still shows 5 GB
First check the online quota at:
https://onedrive.live.com/?v=managestorage
Then compare the account shown there with the account used by OneDrive on Windows:
- Select the OneDrive cloud icon in the taskbar.
- Select Help & Settings (gear) → Settings → Account.
- Check the signed-in email address.
- If it is not the account holding the Microsoft 365 entitlement, select Unlink this PC, then sign in with the correct account.
A different free Microsoft account signed into the Windows client can display a 5 GB quota even when another account owns an active subscription.^4^
If the correct allowance appears online but not in the Windows app, the entitlement is present and the issue is local to the signed-in client; unlinking and signing back in with that same account is the appropriate refresh.
4. Allow time for a restored entitlement
Purchased storage can take up to 24 hours to appear. Refresh Manage storage periodically. If the quota has not updated after 48 hours despite the correct active subscription and account, contact Microsoft Support at https://go.microsoft.com/fwlink/p/?LinkId=528676.^5^
Do not assume the restored allowance must now be exactly 1 TB. Since October 8, 2026, newly purchased or repurchased Microsoft 365 Family and Premium subscriptions receive 2 TB of pooled OneDrive storage, while new Microsoft 365 Pro subscriptions receive 5 TB pooled storage. “Pooled” means the allowance is shared among subscription members, although each member’s files remain private.[^3^](https://support.microsoft.com/accounts-billing/subscriptions/[Subscription ID] "Troubleshoot sharing a Microsoft 365 subscription")
If you are currently over 5 GB, avoid deleting files solely to troubleshoot the quota. Restore the entitlement or copy essential data elsewhere promptly, because remaining over quota can stop uploads and synchronization and can eventually freeze the account.[^1^](https://support.microsoft.com/accounts-billing/subscriptions/[Subscription ID] "What happens when your Microsoft 365 subscription expires | Microsoft Support")
