How to Fix OneNote Error 0xE0001462 Sync Issue on iPad

Product: Microsoft OneNote
Device & OS: iPadOS
Scenario: Synchronizing notes online to OneDrive after installing a new system update on an iPad.
Observed behavior: The synchronization process fails, and OneNote displays error code 0xE0001462 along with additional error identifiers.

Before you start

Verify that your iPad is connected to a stable Wi-Fi or cellular network. Before proceeding with any app resets, manually copy and paste any un-synced text into a local app (like Apple Notes) to prevent accidental data loss.

Solution 1Recommended

Refresh App Authentication and Network Connection

This resolves common authentication and connectivity glitches between OneNote and OneDrive that frequently occur after an iPadOS update.

System updates can temporarily sever the secure connection token between your iPad applications and Microsoft's cloud servers. Re-authenticating your account typically restores proper sync permissions.

Force close Microsoft apps

Swipe up from the bottom edge of your iPad screen and pause in the center. Find the OneNote and OneDrive app preview cards, and swipe them upward to close them completely.

Sign out of OneNote

Reopen the OneNote app. Tap your profile picture or initials in the upper-left corner, navigate to Settings, and select 'Sign Out'.

Re-authenticate your Microsoft account

Tap 'Sign In' on the OneNote home screen and re-enter your Microsoft account credentials. Wait for the app to authenticate and attempt an initial sync.

Refresh App Authentication and Network Connection

Check Microsoft Service Status: If re-authentication fails, check the official Microsoft 365 Service Health status online to ensure there isn't a temporary server outage affecting OneDrive services.

Solution 2

Clear Problematic Attachments and Reinstall OneNote

Use this method if the sync error is caused by corrupted application files, misconfigured permissions, or excessively large attachments.

Frequently Asked Questions

What does OneNote error 0xE0001462 mean?

Error 0xE0001462 indicates a synchronization communication failure between the OneNote application and the OneDrive servers. This is typically triggered by network drops, authentication token expiration, or app misconfigurations following an OS update.

Will reinstalling OneNote on my iPad delete my un-synced notes?

Yes. If your notes have not successfully synced to OneDrive, deleting the application will permanently erase the local, un-synced data. You must manually copy and paste important text into another app before proceeding with a reinstallation.

How can I check if my OneDrive storage is causing the sync error?

You can verify your storage by logging into OneDrive via a web browser on your iPad. Check your storage quota in the settings; if your cloud storage is full, OneNote will not be able to sync new notes, which may trigger synchronization errors.
