The user needs to remove an unexpected Office 2016 trial message appearing in OneNote despite having a newer Office version installed.

How to Fix OneNote Showing an Office 2016 Trial Message

Product: Microsoft OneNote
Device & OS: Windows
Scenario: Launching and using OneNote when the system detects an incorrect or incomplete Office license.
Observed behavior: OneNote displays an Office 2016 Trial message. Manually deleting Office folders and reinstalling does not resolve the warning.

Before you start

Ensure you know the exact Microsoft account credentials associated with your active subscription, and strongly avoid manually deleting any Office installation folders from your C: drive to prevent software corruption.

Solution 1Recommended

Verify Account License and Sign In Again

Check if your currently signed-in account actually holds a valid Office or Microsoft 365 license, as an incorrect login is the most common cause.

Open Account Settings

Launch OneNote, click on 'File' in the top left corner, and select 'Account' from the left-hand menu.

Check Subscription Status

Under 'Product Information', verify if an active subscription is listed. Under 'User Information', check which email address is currently signed in.

Switch Accounts

If the account has no subscription or is incorrect, click 'Sign out', then click 'Sign in' and enter the Microsoft account tied to your actual license.

Frequently Asked Questions

Why does my OneNote say Office 2016 Trial when I have Microsoft 365?

This usually happens when an old Office 2016 product key or a trial license is still cached in your system's registry. Office detects this residual key and displays the trial message, even if you have a valid Microsoft 365 subscription active.

Should I manually delete the Office16 folder to fix this activation error?

No, you should never manually delete the Office16 folder or other Microsoft folders in your C: drive. The Office16 folder is shared by Microsoft 365, Office 2019, and 2021. Deleting it will corrupt your current software installation.

What if my Microsoft account shows no active subscription?

If you verify your account online and it shows no active subscription, you might be signed into OneNote with the wrong email address, or your subscription may have expired. Switch to the correct licensed account in OneNote's Account settings.
