Microsoft is not killing off the OneNote 2016 desktop app after-all.
Microsoft released Office 2019 suite sans an update OneNote for the desktop, instead relying on the separate Universal Windows App for Windows 10.
We are continuing mainstream support for OneNote 2016 beyond October 2020, so that you can continue using the version of OneNote that works best for you,” explains a blog post from the OneNote team.
This means OneNote 2016 will be supported until October 14th 2025 (in extended support). Microsoft is even changing the way OneNote is installed as a result. Starting in March, Office 365 installs that include desktop apps will install the desktop OneNote 2016 version. You can also manually download OneNote 2016 from Microsoft’s site.
The desktop OneNote app is also getting a new dark mode option for both Office 365 subscribers and Office 2019 users this week. You can intsll the app from here – aka.ms/InstallOneNote.
