Teams, SharePoint, & OneDrive - Shared Features & Functions

OneDrive and SharePoint have the same underlying design and features. In fact, OneDrive is actually just a personal SharePoint document library.

When you use Teams, you're using either SharePoint or OneDrive. It's just accessed through a different place.

• SharePoint is the file tool behind a Team and Channel.
  • A team is a group of people gathered to get something big done, like a department or a committee.
  • A channel is basically a subgroup of a team. For instance, a channel can be dedicated to a specific topic, project, etc. 
• OneDrive is what’s used when you share files via Teams Chat.

When sharing files in a Chat, the files are actually uploaded and shared from the sender's OneDrive. You'll find a Microsoft Teams Chat Files folder in your OneDrive. This is where files that you've shared via chat are stored. Its best to try and minimize the amount of file sharing in chats, as shared OneDrive files can become inaccessible if someone leaves the organization and you lose all those files.
