They'll get the OneNote App for Windows 10 instead. It'll also disappear under that circumstance when Office 2019 gets installed.

However, if Microsoft's telemetry indicates that the OneNote 2016 desktop application hasn't been used, then it'll disappear on a future Office 365 update. On the other hand, nothing will change for existing Office users who have the OneNote 2016 desktop application installed, provided that they've used it. With such new installs, the desktop OneNote version won't be there. Both new Office 365 users and future Office 2019 users will get the OneNote App for Windows 10 by default on any new installation of the productivity suite. However, for new users of Office 365, the switchover to the OneNote App for Windows 10 is already happening. Microsoft has previously suggested that Office 2019, its next perpetual-license Office product, will be commercially released in the second half of this year. The switchover to the OneNote App for Windows 10 formally will take place when Microsoft releases Office 2019, according to the announcement. After that date, though, it'll be an unsupported and potentially insecure product. The current OneNote 2016 desktop product will be supported throughout the lifecycle of Office 2016, which means it'll still get updates and security patches until Oct.

Instead, Microsoft is putting its development efforts behind the OneNote App for Windows 10 going forward, according to a Wednesday announcement. Microsoft is planning to stop building its OneNote desktop application, with the current OneNote 2016 product being the last of its kind.
