I have recently been experiencing Sharing File Violations from Excel when saving a file to my ShareFile drive. I am only one using Sharefile. I can save file to my desktop and even to dropbox and do not get this error. And Sharefile has recently not been loading up when machine is started. When it does load it corrupts file manager and I have to reboot. Very Very annoying. Sharefile DriveMapper is critical to my business process and has worked great until recently. I am using Office 365 Excel.
