Check out file when opened from file explorer
We operate a small team through SharePoint Team Site. Sometimes users open the same file From File Explorer and work on it simultaneously. Is there a way to prevent this by checking out the file from SharePoint when opened directly from File Explorer.
If you map a network drive to your team site with Zee Drive then Zee Drive will automatically lock Office documents which will prevent two users from editing the same file at the same time. See http://www.thinkscape.com/Map-Network-Drives-To-Office-365-OneDrive/ for more information.
