The client that I'm working for only has four employees, so it's not that big of a company, but at the same time, the employees are always mobile and thus, an online storage solution is needed. The owner currently uses Microsoft OneDrive Personal edition... I was looking at OneDrive for Business, but everywhere I look, they start talking about how it's useful if you have Sharepoint, which this client does not have... Can he just upgrade to OneDrive for Business (without Sharepoint) and be able to accomplish what he's trying to do? He wants all of his employees to be able to log into the storage space where all of his documents are, BUT what he cannot do now and what he wishes he could do is create user accounts and be able to choose what data each account has access to. Will OneDrive for Business allow this? Do we need Sharepoint for OneDrive for Business? Also, I know this wasn't part of the initial question, but will Outlook's calendar be enough to serve as an online calendar for all of the employees to view and add/remove things from? Any help would be appreciated.
