> Can I continue using OneNote 2016?
Yes — OneNote 2016 isn’t going anywhere. You can continue using it for as long as you want, even if you upgrade to Office 2019. However, after the conclusion of the Office 2016 support lifecycle (October 13, 2020 for mainstream support and October 14, 2025 for extended support) we will no longer provide support, security updates, or fixes for OneNote 2016.
