I wonder if moving this thread to 'Mobile Products' will better enhance the chance of receiving more exposure and assistance?
The files were likely encrypted using File and Removable Media Protection. Because the device was detected a removable media, a prompt would have been displayed and the option to encrypt the device was selected. There is no way to decrypt these files from home. You will need to contact you IT department to enable the option to allow you to decrypt the files.
Can you tell me what need to be enabled by IT Department. I am also facing same issue and my IT Department is not aware about it.
