Sharepoint in Microsoft 365

This tool is a cloud-based service, hosted by Microsoft, for businesses of all sizes. Instead of installing and deploying SharePoint Server on-premises, any business can subscribe to a Microsoft 365 plan or to the standalone SharePoint Online service. The employees can create sites to share documents and information with colleagues, partners, and customers.

Organizations use Microsoft SharePoint to create websites. It can be used as a secure place to store, organize, share, and access information from any device. All you need is a web browser, such as Microsoft Edge, Internet Explorer, Chrome, or Firefox.
