One Drive capacity 1 TB but 88GB usage showing storage is full ??

This usually happens for one of these reasons:

1. OneDrive is signed in with a different Microsoft account than the one that has the 1 TB subscription.
2. The storage quota has not refreshed yet after a subscription change, renewal, or added storage.
3. A shared folder in OneDrive is counting against the account’s storage.
4. Items in the OneDrive Recycle Bin are still using storage.
5. A subscription or promotional storage benefit expired.

Try this in order:

1. Check that the Microsoft 365 subscription is active on the same Microsoft account used in OneDrive.
   • Open the Microsoft account services page and confirm the subscription is active.
   • Then check the Microsoft storage area in the account dashboard to confirm the quota and usage.
2. Check OneDrive storage details.
   • In OneDrive on the web, open Manage your OneDrive storage.
   • Review what is taking space and empty the Recycle Bin if needed.
3. Verify the signed-in account in the OneDrive app.
   • Select the OneDrive cloud icon in the taskbar.
   • Go to Help & Settings > Settings > Account.
   • Confirm the account shown there is the same account that owns the 1 TB plan.
4. If the account is wrong, unlink and sign in again with the correct account.
   • In OneDrive > Settings > Account, select Unlink this PC.
   • Sign in again with the Microsoft 365 account that has the 1 TB storage.
   • Unlinking does not delete files stored online.
5. If the account is correct, wait up to 24 hours for the storage quota to update.
   • If it still shows full after that, unlink and relink OneDrive to refresh the app.

Important effects of being over quota:

• New files cannot be uploaded, edited, or synced.
• Existing files remain available but become read-only.
• If the account stays over quota for a long period, OneDrive can eventually be frozen or files may be deleted.

If the web account dashboard shows the correct 1 TB quota and low usage, but the OneDrive app still says storage is full after waiting and relinking, use Contact Microsoft Support from the support page.
