OneDrive storage full and sync stopped: check cloud and local space
What to do first
First establish whether the shortage is on the PC or in the cloud. Removing local copies alone does not resolve an exceeded cloud quota; preserve needed content before deciding what to remove.
This is a general troubleshooting guide, not an announcement of a current outage.
Affected products and symptoms
- Product
- Microsoft OneDrive
- Versions and conditions
- Personal and work or school OneDrive; Windows sync app and web
Symptoms
- OneDrive reports that its storage is full
- New files stop syncing or cloud files cannot be edited
Causes and conditions
Cloud quota and local disk capacity are separate limits. A subscription change or organizational storage limit can also change the available cloud allowance.
Before you start
- Record the OneDrive account and exact capacity message
- Identify unsynced recent work and cloud files that must be retained
Precautions
- Verify preserved copies before permanently deleting recycle-bin items
- Reconfiguring the sync app does not reduce cloud usage

Step-by-step instructions
Open the OneDrive notification-area icon and identify the personal or work/school account showing the warning. Record which account is affected when several are connected.
Distinguish a cloud-storage warning from a message about the computer's disk being full.
Record the affected account, web usage, local free space and unsynced files. Spare capacity in another personal or work account does not explain this warning. Match the signed-in web account to the desktop icon. Use current plan/organization quota displays rather than historical limits and save the complete error.
Sign into OneDrive on the web with the same account. Use its storage management or storage-used view to compare the allowance with current usage.
For personal accounts, Microsoft cloud storage includes content beyond the OneDrive folder, such as Outlook.com attachments. Ask the administrator about organization-controlled limits.
Freeing local space does not increase a full cloud quota. Spare cloud quota with a full PC calls for local-storage measures. Edits made while sync is blocked may not be uploaded; the web can contain an older file with the same name. Check time and content and independently copy unsynced originals before cleanup.

The personal OneDrive recycle bin affects usage. Verify retained copies before permanently deleting only unneeded items. For shared files, confirm ownership and the affected quota account; do not bulk-delete folders when deletion impact is unclear.
In File Explorer, inspect the properties of the drive containing the OneDrive folder. If web quota is available but that drive is full, address local working space.
Making synced files online-only addresses local capacity. Do not remove unsynced files on the assumption that the website already holds them.
Download or copy files you want to retain to storage outside OneDrive before removing their cloud copies. Open the preserved files to verify them.
Desktop and Documents may themselves be inside OneDrive. Verify the destination path and coordinate any changes to shared files.
Separate disposable files, files needing independent retention and files shared with active users. Verify that retained copies are outside synchronization scope, including redirected Desktop/Documents locations. Deletion inside the sync folder propagates to cloud and other devices, so inspect one intended removal before broad cleanup.

Remove only confirmed unwanted content through the website and review the OneDrive recycle bin. For personal storage, its contents count toward usage; permanently remove only items you no longer need.
This is separate from the PC recycle bin. If the remaining content is needed, consider additional capacity or administrator assistance instead of further deletion, then recheck the updated usage.
If required data cannot be removed, consider storage for the actual account or ask the organization administrator. Another account plan may not affect this quota. After any addition, verify the displayed limit and sync; purchase completion alone does not protect pending data.
After usage is below the allowance, save a small test document in the OneDrive folder. Check that the same name and content appear on the website.
A disappearing warning without the new file arriving is incomplete recovery. Record any remaining sync error and investigate it separately.
After usage updates, confirm quota headroom and sync state. Other errors or pausing can persist. Upload a small test document and open its matching content on the web, then another device if needed. Warning disappearance alone is insufficient. Report account type, quota/usage, local space, last success and unsynced originals, retaining the latter.
Check the result
- Web usage is within quota and a new upload succeeds
- The Windows test file appears with the expected content on the web
- The affected account is below quota and its new test document content is verified on the web
If the problem continues
- If the allowance does not update, verify the subscription or administrator setting and displayed usage
- If sufficient quota remains but sync is stuck, investigate the remaining error message

Frequently asked questions
Does Free up space reduce my cloud usage?
Making files online-only reduces local copies. Check and address cloud usage separately on the website.
Why did emptying the PC recycle bin not help?
OneDrive has a separate web recycle bin. Check which storage limit is exceeded and review the relevant cloud items.
Can I delete a web file when a PC copy exists?
A copy inside the sync folder may be removed by propagation. Make and verify an independent copy outside OneDrive and discuss deletion scope and retention with affected collaborators.
