Solution 1Recommended

Verify Subscription and Test Web Uploads

Determine whether the issue lies with your Microsoft account's storage allocation or just the local desktop sync client by testing the web version.

Sometimes the desktop application fails to update its local cache, while the actual account storage has been successfully upgraded on the cloud.

1
Log into your Microsoft account

Navigate to the Microsoft account subscription page and sign in. Confirm that the 400 GB storage add-on is listed as 'Active'.

2
Access OneDrive on the web

Go to the OneDrive website and sign in. Check the storage capacity indicator located at the bottom-left corner of the screen.

3
Test a web upload

Click 'Upload' and attempt to upload a new file directly through the web interface. If this fails and reports that your storage is full, you must contact Microsoft OneDrive Support to investigate your account's storage allocation.

Frequently Asked Questions

How long does it take for extra OneDrive storage to show up?

While storage upgrades are usually applied immediately, it can sometimes take up to 24 to 48 hours for the additional space to reflect across all Microsoft servers and your local desktop client.

Why does my PC say OneDrive is full when I just bought storage?

Your local desktop application might be out of sync with your Microsoft account's cloud data. Resetting the OneDrive app or signing out and back in forces the software to refresh and recognize the new storage limit.

Can I transfer my OneDrive storage add-on to a different Microsoft account?

No, Microsoft storage subscriptions and add-ons are strictly tied to the specific account used during the purchase. You must ensure you are logged into that exact account on your desktop to utilize the space.
