Solution 1Recommended

Check Storage Metrics and Empty Both Recycle Bin Stages

Hidden files like document version history and second-stage recycle bin contents often consume your OneDrive quota. Clearing these can permanently resolve the red X warning.

In OneDrive for Business, storage quotas are calculated based on active files, multiple versions of saved documents, and deleted files held in both the primary and secondary recycle bins. Deleting files from your main folders only moves them to the recycle bin, meaning they still count against your storage limit.

1
Access OneDrive Settings

Open OneDrive in your web browser, click the gear icon in the top right corner, and select 'OneDrive settings'.

2
View Storage Metrics

Navigate to 'More Settings' (or Site Settings) and click on 'Storage Metrics' to see a detailed breakdown of what is consuming your space, including version histories.

3
Empty the Primary Recycle Bin

Click on 'Recycle bin' in the left-hand navigation pane, then click 'Empty recycle bin' to clear the first stage of deleted files.

4
Clear the Second-Stage Recycle Bin

Scroll to the bottom of the Recycle Bin page, click the link for the 'Second-stage recycle bin', and empty it to permanently free up your storage.

Check Storage Metrics and Empty Both Recycle Bin Stages
Storage Successfully Reclaimed: Emptying the second-stage recycle bin permanently removes files and immediately reclaims the hidden storage space, allowing OneDrive to resume syncing without the red X error.

Frequently Asked Questions

What does the red X mean on my OneDrive folders?

A red X icon indicates that a file or folder cannot sync with the cloud. This is most frequently caused by the OneDrive account running out of storage quota, preventing new or modified files from uploading.

Why does OneDrive still say it is full after I deleted large files?

When you delete files in OneDrive, they are moved to the recycle bin and still count against your overall storage quota. You must manually empty both the primary and second-stage recycle bins to actually free up space.

How do I access the second-stage recycle bin in OneDrive?

Log in to OneDrive on the web, click on 'Recycle bin' in the left menu, and scroll to the very bottom of the item list. Click the link that says 'Second-stage recycle bin' to view and delete permanently retained files.

Does file version history count towards my OneDrive storage limit?

Yes, OneDrive saves multiple historical versions of your documents, and each version consumes part of your storage quota. You can review and delete old versions by accessing the 'Storage Metrics' page in your OneDrive settings.
