Before you start

Verify your Microsoft account storage quota on the web to ensure your account is not frozen due to exceeding storage limits, and confirm whether you are logging in with a personal or work/school account.

Solution 1

Use Private Browsing and Check Storage Status

Use this solution to rule out browser cache issues and verify if a full storage quota is preventing file creation on OneDrive Web.

Open a Private Window

Launch your web browser and open a New Incognito or InPrivate window. Navigate to the OneDrive website and sign in.

Check File Creation

Attempt to create a new document or open the settings menu. If it works, clear your standard browser cache and cookies.

Verify Storage Quota

If you still cannot create files, look at the bottom-left corner of the OneDrive web interface to check if your storage is full. If full, you will need to delete unnecessary files or upgrade your storage plan.

Frequently Asked Questions

What causes OneDrive error code 0x8004def5?

This error is typically caused by corrupted cached credentials, network connectivity issues disrupting the authentication process, or conflicts when both personal and work accounts are configured improperly on the same desktop client.

No, resetting the OneDrive application only restores its internal settings to default and clears configuration caches. It does not delete your local files or any previously synced data.

Why can't I create files on the OneDrive web portal?

If you cannot create files on the web, it usually means either your browser's cache is causing a script error, or your Microsoft account has exceeded its storage quota, effectively freezing your ability to upload or create new items.
