Hi, we have 3 computers using Windows10 and Office 365 and we use Onedrive to sync files and folders. It works perfectly with 2 of the computers, but Onedrive on the third one keeps disappearing from file explorer. We have followed the problem solving tips and can get Onedrive back but it won't stay where it's supposed to be! This also causes major sync problems as every time the Onedrive files are reloaded it creates duplicates if the files have been moved from one folder to another in the meantime. I've just realised that this computer is set up to not have to use a password to log in at start up - is it at all possible that this would be causing the problems? We can access Outlook etc with no problems on that computer and don't have to log in first. Has anyone else had this issue?
