To do this, you will create a folder somewhere in the shared folder, move all the files in the OneNote folder to that location, then move them back. Finally, you will need to “deoptimize” (or, and I love this, de-dedup) the files.Next, have everyone close OneNote on their systems.You will need to exclude these extensions: *.one, *.onebin, *.onetoc2.See the “Modifying Data Deduplication volume-wide settings” section. Here are some details on configuring that with PowerShell.

You will need to set an exception for the OneNote file extensions in Windows Server 2012 Data Deduplication.To resolve this problem you will likely need your administrator involved:

When we enabled the exception for OneNote files in the data deduplication feature and then moved the OneNote files from one folder to another and then back (which is required to de-optimize the files), the problem went away. Tabs would start disappearing for other users when multiple users were editing the files. What we found was the deduplication was corrupting the OneNote index (toc) on the server and each time someone went to make changes to the OneNote file on the server. It is a form of compression at its simplest which is to say it is a mechanism to allow you to stick more stuff on a computer or server disk. At its simplest, it is a way to reduduplicate files and similar streams of data on a disk.

The cause as it turned out was something called Windows Deduplication. It is especially prevalent when they moved to OneNote 2016. Recently, a customer I work with asked me to investigate why the tabs in their shared OneNote notebooks were disappearing.
