Click on Sync All to sync all of your shared notebooks, or click on Sync Now next to the specific notebook you want to sync. How do I automatically sync OneNote?

Microsoft has released KB5002500 for OneNote 2016 to stop the program from crashing whenever users tried to sync notebooks that were shared to them from newer versions of Microsoft OneNote.

Would that be a way to keep those files in sync?<BR><BR>OneNote has an option to share a notebook on the web through SkyDrive, it's just not available yet. So that might be a good option eventually.
