- Product
- Microsoft OneNote
- Device & OS
- not provided
- Scenario
- Attempting to sync OneNote notebooks after purchasing additional Microsoft account storage.

Ensure you have your PayPal transaction ID and login credentials for the exact Microsoft account associated with your OneNote notebooks ready.
Verify Account Storage and Force a OneNote Sync
Use this solution to ensure the newly purchased storage is applied to the correct account and to refresh the OneNote app's connection to the server.
Sometimes, subscription updates take a little time to reflect across all apps, or the app might be stuck holding onto old account cache data. Signing out and back in forces OneNote to retrieve your latest Microsoft 365 storage quota.
Open a web browser, go to the Microsoft account management page, and sign in. Navigate to the 'Services & subscriptions' section to confirm your Microsoft 365 renewal or additional storage is listed as active.
Open the OneNote application. Click on your profile picture or account name in the top right corner, then select 'Sign out' or 'Sign out of all accounts'.
Close OneNote completely and reopen it. Sign back in using the exact Microsoft account that holds the newly purchased storage.
Right-click on the notebook that was failing to sync and select 'Sync This Notebook Now' to verify if the storage error is resolved.

Contact Microsoft Billing Support for a Correction or Refund
If your payment was processed via PayPal but the storage was not added to your Microsoft account, you will need to contact support to correct the error or initiate a refund.
Use WPS Office as a Lightweight Alternative for Document Management
If you are experiencing ongoing storage limitations or subscription sync issues with Microsoft 365, consider switching to WPS Office. It provides a lightweight, highly compatible, and free alternative with its own built-in cloud storage for seamless document creation and management.

- 3. Import Your Existing Documents: Open your existing Microsoft Office files directly in WPS Office without losing any formatting.

Frequently Asked Questions
Why doesn't my Microsoft storage update immediately after purchase?
Storage updates can sometimes experience server-side delays. It may take up to 24 to 48 hours for new storage quotas to fully propagate and synchronize across Microsoft services, including OneDrive and OneNote.
Can I use multiple Microsoft accounts with OneNote?
Yes, you can add multiple accounts to OneNote. However, you must ensure that the specific notebook you are trying to sync is stored on the Microsoft account that holds the active storage subscription.
How do I request a refund for a Microsoft purchase made through PayPal?
You can request a refund directly through the Microsoft account management portal under your order history. If the order isn't showing up, you can contact Microsoft billing support or open an 'Item Not Received' dispute in your PayPal Resolution Center using your transaction ID.
