Hello
Onenote 2016 has an option called "save and backup" where you can define a folder (by default C:\Users"username"\AppData\Local\Microsoft\OneNote\16.0\Backup ) and time interval of automatic notebook backups.
I'm trying to implement this setting using Office 2016 group policy templates. And it applies successfully the settings I want (folder, time interval and number of versions).
Now the problem is the following;
This GPO will apply to a large number of users and redirects to a path in the userprofile. As expected I need to place a variable like %username% in the path I want.
The problem is, when using a variable, the Onenote cannot backup the notebook, it gives the following error;

How can I bypass this issue?
If I use a path without %username% it works like a charm, so it is not a problem of "denied acccess" like the error says.
One last question, cannot find this backup/save options in Onenote for MAC, it doesn't exist?
If it not configurable, what's the default path where Onenote stores the notebooks on MAC?
On both scenarios, they are synced with office 365 accounts. But on 365, it is only a pointer, not the notebook itself.
Even if it has the notebook, I also need centralized local backup.
Thank you
