We would like to shed my on premise file storage and have all our users use OneDrive for Business. We would like to have a folder created in everyone's OneDrive that they can not accidentally share files from consider it a "safe' folder. The user would have to deliberately move the document out of the "Safe" folder to another area or folder before they could share it .

This "Safe" folder would be added protection to prevent theaccidental/unintentional sharing trade secrets, personal information, etc...
