Office 365 – Microsoft Team, the chat based workspace

Microsoft has introduced a new collaboration feature on Office 365 called Microsoft Team.

Microsoft Team is built on top of Office 365 Groups, SharePoint, Exchange and OneNote (plus off course Azure AD for the identity/authentication)

  • Enterprise E1, E3, E4 (for those still with this retired SKU) and E5
