How to Fix OneNote Sign-In Error Code 0 and Correlation ID

Product: Microsoft OneNote
Device & OS: not provided
Scenario: Attempting to authenticate and sign in to the OneNote application.
Observed behavior: The sign-in process fails, displaying a correlation ID, timestamp, DPTI, error tag, and error code 0.

Before you start

Before troubleshooting, ensure you have your correct Microsoft account credentials ready and verify that your internet connection is active and stable.

Solution 1Recommended

Isolate the Issue with OneNote for Web and Other Devices

Determine if the sign-in issue is localized to your specific device or app by testing the web version and alternative networks.

Authentication errors can stem from a localized app glitch, a network block, or an account-level issue. By isolating the environment, you can quickly identify the root cause.

Test OneNote for the Web

Open your web browser, navigate to onenote.com, and attempt to sign in with your Microsoft account to see if the web version works properly.

Check Other Office Applications

Open Word or Excel on the same device and try signing in. Take note of whether the error appears before or after entering your account details.

Switch Your Network Connection

Disconnect from your current Wi-Fi and connect to a different network, such as a mobile cellular hotspot, to rule out strict firewall or DNS blocking.

Verify Account Activity

Log in to your Microsoft account dashboard on a browser to confirm your account is active, verifying it hasn't been locked due to a long period of inactivity.

Isolate the Issue with OneNote for Web and Other Devices

Diagnostic Tip: If you can sign in successfully on the web but not in the desktop app, the issue is likely related to the app's cached credentials on your device.

Solution 2

Clear Cached Office Credentials

Remove old or corrupted sign-in tokens from your device to force the app to establish a fresh authentication connection.

Frequently Asked Questions

What does Error Code 0 mean in OneNote?

Error Code 0 in OneNote typically indicates a generic network or authentication failure where the application cannot establish a secure connection with Microsoft's sign-in servers.

Why am I seeing a Correlation ID in my sign-in error?

A Correlation ID is a unique tracking code generated by Microsoft servers. While it doesn't solve the problem directly, you can provide this code to Microsoft Support to help them track the exact point of failure in their system logs.

Can a blocked network cause OneNote authentication to fail?

Yes, enterprise firewalls, VPNs, or strict antivirus settings can block the specific ports Microsoft uses for authentication, resulting in sign-in errors and a correlation ID display.

Will my unsynced notes be lost if I clear my credentials?

Clearing credentials primarily resets your login state, but it is always recommended to back up offline notebooks or manually copy unsynced pages to a local document before performing any app resets to prevent data loss.
