- Product
- Microsoft OneNote
- Device & OS
- not provided
- Scenario
- Accessing synchronized notes after migrating apps and data to a newly purchased smartphone.
- Observed behavior
- OneNote fails to open the previously saved notes, potentially due to requesting additional permissions or experiencing account sync errors.
Ensure your new phone is connected to a stable Wi-Fi network and verify whether you are using a personal or work-related Microsoft account before beginning.
Grant App Permissions and Verify Account Details
Use this solution to ensure OneNote has the necessary system permissions to access device storage and that the correct Microsoft account is actively syncing.
When transferring data to a new phone, security settings and app permission models often reset. This requires you to manually grant OneNote access to your device's storage and background synchronization services.
Navigate to the Settings app on your new phone and look for the 'Apps' or 'App Management' section.
Scroll through the list of installed applications and tap on 'OneNote'.
Tap on 'Permissions' and ensure that storage, network, and background data access are allowed.
Open the OneNote app, go to the account settings, and confirm you are signed into the exact Microsoft account (personal or work) associated with your notes.

Reinstall the OneNote Application
Reinstalling the app clears out corrupted cache data and forces a fresh connection to Microsoft servers, which can resolve persistent sync issues.

Frequently Asked Questions
Why does OneNote require new permissions on a new phone?
Security settings and app permission models typically reset or change when transferring data to a new device. This security feature ensures that apps only access what you explicitly allow on your new hardware.
Will I lose my notes if I uninstall the OneNote app?
If your notes were successfully synchronized to your Microsoft account (OneDrive) prior to uninstalling, they are safe in the cloud. However, any recent offline changes that haven't been synced will be permanently lost during uninstallation.
Can I use both a personal and work account in the OneNote mobile app?
Yes. You can add multiple accounts in the OneNote app settings by navigating to the account profile section and selecting 'Add Account', which allows you to switch between work and personal notebooks seamlessly.
