Office 365 Groups
Groups in Office 365 connects users with the colleagues, information and applications they need to get more done together. Groups are open by default to enhance discoverability and sharing, but users can also create private groups for sensitive content.
What is Microsoft 365 Groups?
Microsoft 365 Groups is the cross-application membership service in Microsoft 365. At a basic level, a Microsoft 365 Group is an object in Azure Active Directory with a list of members and a coupling to related workloads including a SharePoint team site, shared Exchange mailbox, Planner and Power BI workspace. You can add or remove people to the group just as you would any other group-based security object in Active Directory.
