Microsoft Teams
Microsoft's chat, meeting, and collaboration application, layered over SharePoint, Exchange, and Entra ID.
Every team creates a SharePoint site and a group behind the scenes, which is why uncontrolled team creation produces sprawl that is hard to govern later.
Chat is also business communication subject to retention and discovery obligations, a fact frequently missed until the first legal request arrives.
Where this comes up
Microsoft Teams sits inside our microsoft 365 and cloud work. If you are trying to work out what this means for your own environment rather than in the abstract, that is the page worth reading next, and a short call will get you a straight answer faster than either.
