These files also are locally cached, which permits offline access to them. Storage for notebook files using the OneNote App for Windows 10 happens on OneDrive, which is Microsoft's public cloud-based storage service. Offline storage, though, is just not a capability that the OneNote App for Windows 10 will get, despite user pleadings to add it. For instance, a lawyer indicated that he can't save files to a public cloud-based storage service, and a government worker made the same claim. In particular, many pointed out that they need to save OneNote notebook files in their local offline storage. Reader comments in reaction to Microsoft's announcement weren't very positive about the switch. Microsoft is adding some of them, but it urged users to give feedback on any missing features that are important for them to see in the updated OneNote App for Windows 10. Microsoft freely admits that the OneNote App for Windows 10 still lacks some features that are currently available in the OneNote 2016 desktop application. There also will be improved content syncing between devices. An example might be tagging some saved portion of text as being 'Important.' Another feature will let end users preview Office files that get saved using the OneNote App for Windows 10. Coming this summer will be the ability to insert and search for tags. Microsoft touted the OneNote App for Windows 10 because it's frequently updated with new features. 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.

Onenote for desktop not that shitty app
