The user needs to resolve a synchronization error preventing a shared OneNote notebook from connecting to the server.

How to Fix OneNote Sync Error 0xE0001464 When Connecting to the Server

Product: Microsoft OneNote
Device & OS: not provided
Scenario: Attempting to synchronize a shared notebook or trigger a manual sync.
Observed behavior: The synchronization process stops partway through, displaying error code 0xE0001464 indicating it cannot connect to the server.

Before you start

Manually back up any unsynchronized content by copying it to Word, WPS Writer, or OneNote for the web before proceeding, as closing notebooks with un-synced data will cause permanent data loss.

Solution 1Recommended

Clear Cached Office Credentials in Windows

Removing outdated or corrupt Microsoft Office identities forces OneNote to re-authenticate and establish a fresh connection to the server.

Windows Credential Manager stores your login tokens. When these tokens expire or become corrupted, OneNote may fail to connect to OneDrive or SharePoint, resulting in the 0xE0001464 error.

Close the affected notebook

In OneNote, go to 'File' > 'Info' > 'Settings' next to your notebook and click 'Close This Notebook'. Repeat this for any other notebooks experiencing the issue.

Sign out of Office

Sign out of all Microsoft Office accounts within the application, and then completely quit OneNote and any other open Office apps.

Remove stored credentials

Open the Windows 'Control Panel', navigate to 'User Accounts' > 'Credential Manager', and click on 'Windows Credentials'. Locate any entries related to Microsoft Office and click 'Remove'.

Restart and sign in

Restart your computer. Open OneNote, sign in with your Microsoft account, and go to 'File' > 'Open' > 'OneDrive' to open your notebook again and resume syncing.

Clear Cached Office Credentials in Windows

Authentication Restored: Clearing credentials forces a complete refresh of your server connection without deleting your actual cloud data.

Solution 2

Switch to a Different Network Connection

Bypass potential local network restrictions or unstable Wi-Fi by trying an entirely different connection.
