How to Fix OneDrive Not Syncing After Additional Storage Purchase
Question details
The user purchased an additional 400 GB of OneDrive storage, but the system continues to show the previous 1 TB limit and files have stopped syncing.

- Product
- Microsoft OneDrive
- Device & OS
- not provided
- Scenario
- Attempting to utilize newly purchased cloud storage space to resume file synchronization.
- Observed behavior
- The OneDrive desktop application fails to recognize the new storage limit and blocks further file syncing, functioning as if the storage is still full.
Ensure you are logged into the exact Microsoft account used to purchase the additional storage, and allow up to 24 hours for the transaction to fully process on Microsoft's servers.
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.
Navigate to the Microsoft account subscription page and sign in. Confirm that the 400 GB storage add-on is listed as 'Active'.
Go to the OneDrive website and sign in. Check the storage capacity indicator located at the bottom-left corner of the screen.
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.

Reset or Reinstall the OneDrive Desktop App
Use this solution if web uploads are working correctly but your desktop client still shows that your storage is full.

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.
