I have a sales team of 50 people and they all have different data. They sometimes mail me, and sometimes i need to see the progress. And most of the time they are not in the office. Can i have one computer with different users. and each sales executive will have their respective user and can save their excel sheet on desktop and all other data. They would not be able to see each other's data but i as an administrator would be able to go any user's desktop or documents to only read that file without knowing their passwords. i dont want to put it on icloud drive or mail me. Sometimes they send me the sheets i really dont need to see, but they have to because i might need someday. is there any solution to that ?
