Disable 'open in Explorer' and the ability to Map to Map Drive
When mapping a drive via Explorer, the drive disconnects after some time for SharePoint users. Why wouldn't you create some solution that keeps the user always logged in?
I deployed that option and it was a nightmare. The drive would keep giving errors after reboots or not have stable connection.
Hi Leo. Try Zee Drive for mapping network drives to SharePoint Online and OneDrive for Business. Zee Drive keeps users signed in and the drives persistent. More information here: http://www.thinkscape.com/Map-Network-Drives-To-Office-365-OneDrive/
