That is to say the file isn’t actually on OneDrive as a file that you can open.
The important thing is that you have a full copy of the notebook on your local machine and it’s only the changes that are being synced. When OneNote does its native ‘OneDrive sync’ it actually only sends the changes up to the cloud which subsequently then sends these changes out to the other devices. Normally, cloud sync services like OneDrive or Dropbox copy the newest version of the file up to the cloud and then send it out to all the other devices logged in to that account. There is a lot of magic going on behind the scenes when OneNote & OneDrive are syncing your changes between machines.
What they tend to do is copy their notebooks from wherever they used to store them and then paste them into their OneDrive folder. However, due to the smart way that OneNote handles synchronisation and coupled with the fact that it’s generally called OneDrive sync – OneDrive of course being Microsoft’s cloud storage platform – confusion can ensue when people start to migrate to using OneDrive for notebook sync. To get the most power out of OneNote you want to be able to synchronise the contents of your notebooks between devices and possibly share them with other people.Ĭloud based save, sync or sharing is a standard requirement for most software these days and OneNote is no exception by offering such a feature.
