What is the relationship between Microsoft Teams and SharePoint?
Every Microsoft Teams team automatically creates a SharePoint site behind the scenes. Files you share in Teams channels are actually stored in a SharePoint document library — Teams is the collaboration interface, SharePoint is the storage layer. Standard channels share a SharePoint site; private channels get their own dedicated SharePoint site collection. This means SharePoint permissions, governance, and storage policies apply to all Teams file content. Organizations should govern Teams and SharePoint together, not as separate platforms.
