OneNote send pages opens old outlook

Hi

I have switched to the new outlook, but whenever I send a page from OneNote, it opens the old outlook and it regularly doesn't send out the page correctly. How can I make sure it always opens the new outlook?

Thanks and BR,

Céline

    Hi Céline,

    This happens because the "Email Page" feature in the classic desktop version of OneNote relies on deeply integrated MAPI hooks, which default to Classic Outlook. Since New Outlook handles system protocols differently, you need to adjust your default app and protocol handlers in Windows to route these actions correctly.

    Try these steps to fix the routing:

    • Set New Outlook as the Default Mail Handler: Open Windows Settings (Win + I) > Apps > Default apps. Scroll down or search for Outlook (New). Click it and ensure it is set as the default application for the MAILTO protocol and all default mail extensions.

    • Enable the New Outlook Toggle: Open Classic (old) Outlook. Look at the top right corner for a toggle that says "Try the new Outlook". If it is turned off, switch it to On. This updates the internal Windows registry registry paths to intercept MAPI requests from other Office apps like OneNote.

    • Use the Share Built-In Feature: If the classic "Email Page" button continues to look for the old software layout, try using the native Windows integration shortcut instead. Click the Share button at the top right corner of OneNote and select Email Page or choose Outlook directly from the modern Windows share flyout panel.
