I have tried for three days now to open up my onenote notebooks in outline. I have tried using one drive for business. I see the folder to open it with, yet when I click on the folder nothing happens. I have tried using the sharepoint server link and when I add it nothing happens either. I uninstalled and reinstalled outline twice and install one note, yet I paid for this one and want to be able to use it. I can open the notebooks on my iPad, but I need them open on my mac. Any assistance would be appreciated.
