- Scenario

- Observed behavior
- The OneDrive client stops syncing at the 1 TB threshold, failing to recognize or utilize the extra 400 GB of purchased storage.
Before troubleshooting, ensure you are signed into the correct Microsoft account that holds the active Microsoft 365 Family subscription and the additional storage purchase.
Verify Storage Allocation and Test Web Uploads
Check your account online to confirm the extra storage is active and test if the issue is limited to the desktop app.
Open a web browser and log into OneDrive online using your Microsoft credentials.
Click the gear icon (Settings) > Options > Manage storage to verify your total available capacity reflects the 1 TB plus your extra 400 GB purchase.
Attempt to upload a large file directly through the web interface to see if it successfully bypasses the 1 TB limit.
Reset or Reinstall the OneDrive Desktop App
If web uploads are successful but the desktop client fails, resetting the app can force it to refresh its connection to your account's updated storage quota.
Contact Microsoft OneDrive Support
If your web account also shows it is full or fails to upload, the storage quota may not be provisioned correctly on Microsoft's end.

Frequently Asked Questions
Why doesn't OneDrive recognize my purchased extra storage?
It can take up to 24-48 hours for newly purchased storage to reflect across all Microsoft servers. Additionally, the local OneDrive desktop client may need to be reset to sync the updated quota from the cloud.
Can I combine Microsoft 365 Family storage with extra purchased storage?
Yes, Microsoft allows Microsoft 365 Family and Personal subscribers to purchase up to an additional 1 TB of OneDrive storage, which is added to your base 1 TB quota per user.
What happens to my files if OneDrive reaches its storage limit?
Once the limit is reached, OneDrive stops syncing new files or uploading changes to existing files. However, your previously synced files remain safe and accessible in the cloud.
How do I force OneDrive to sync after upgrading my storage?
You can pause and resume syncing from the OneDrive system tray icon, or fully close and restart the OneDrive application to force it to check the server for your newly updated storage quota.
