About Microsoft SharePoint
The Microsoft 365 layer that holds the documents.
SharePoint shipped in 2001 as Microsoft's intranet, document-management and team-collaboration platform, and it now sits at the centre of Microsoft 365 alongside Teams, OneDrive and Outlook. Microsoft has reported more than 250 million users on the platform across the M365 estate, with sites covering classic intranets, communication portals, project workspaces, departmental document libraries, and the lightweight lists that act as the database behind countless Power Apps and Power Automate flows.
For most M365 shops SharePoint is no longer a thing people open on its own. Every Microsoft Teams team creates a SharePoint site under the hood for its files. OneDrive for Business is a per-user SharePoint site. Communication sites carry the company intranet. Document libraries hold contracts, policies, drawings and engineering specs. And lists hold the project trackers, request queues and asset registers that small Power Automate flows tick through every night. The Microsoft Graph SharePoint surface exposes sites, lists, listItems, drives, items, columns, contentTypes, pages and permissions. Pulling that into a warehouse is how IT, compliance and the records-management lead see the whole estate at once, instead of clicking through admin centres and tenant search.
