Question details

The user needs to resolve a synchronization issue in OneNote 2016 where the application fails to connect or sync notebooks.

Product: OneNote 2016
Device & OS: Windows 7
Scenario: Attempting to synchronize existing OneDrive notebooks, or creating and sharing new notebooks in OneNote 2016.
Observed behavior: OneNote 2016 displays a "not connected" status and returns error code 0x803d0014 during synchronization attempts.

Before you start

Ensure your Windows 7 system is fully updated and check your internet connection before modifying any registry settings or repairing your Office suite.

Solution 1Recommended

Enable TLS 1.1 and TLS 1.2 via Registry Keys

Updating your system's security protocols is the most effective way to restore the connection to Microsoft servers on older operating systems.

Windows 7 does not support modern TLS security protocols by default. Microsoft 365 services require these protocols to authenticate and synchronize data safely.

Download the Easy Fix Tool

Navigate to the official Microsoft support site and download the Easy Fix Tool designed for adding TLS support to Windows 7.

Run the utility

Double-click the downloaded tool and follow the on-screen prompts to automatically inject the TLS 1.1 and TLS 1.2 keys into your registry.

Restart your computer

Reboot your Windows 7 device to ensure the new registry settings take effect completely.

Verify OneNote synchronization

Open OneNote 2016, navigate to your notebook list, and check if the connection error has been resolved.

System Reboot Required: Do not skip the system restart. The new registry keys for TLS 1.1 and TLS 1.2 will not be active until the computer reboots.

Solution 2

Clear Office Identity Cache and Reconnect

Corrupted account credentials can prevent OneNote from connecting to OneDrive or SharePoint, causing synchronization to fail.

Solution 3

Upgrade to a Supported Operating System

Modern Microsoft 365 services and Office apps may not fully support Windows 7, resulting in persistent synchronization errors.

Free Microsoft Office alternative
