Office 365 SharePoint is a cloud-based service that helps organizations share and collaborate with colleagues, partners, and customers. With Office 365 SharePoint, you can access internal sites, documents, and other information from anywhere—at the office, at home, or from a mobile device.

   Larger businesses use site collections in the same way small businesses use subsites. A small business with advanced security needs and strong technical skills might also want to
