Hi,
In the new Outlook, the Send to OneNote box shows every notebook linked to your account, even if they’re closed. To clean it up, you can move old notebooks out of your OneDrive "OneNote Notebooks" folder so Outlook won’t list them, or clear OneNote’s cache to reset the list (though anything still stored in OneDrive will come back). Since there’s no way to filter the list, the easiest fix is to keep only the notebooks you use in the main OneNote folder and archive the rest, then rely on the "Recent Sections" at the top for quick access.
Kind regards,
