As Microsoft released the new OneDrive syncclient (OneDrive Next Generation Syncclient), we've created the abbility to choose as a Workspace 365 administrator which sync client you would like to use in the Documents app.

As these setting only changes the formatting of the url;

• The old client (grvopen://)
• The new client (odopen://)

You have to make sure that you have changed these settings in the SharePoint admin tenant the same as in Workspace 365.
