This article is meant to be a simplified explaination on Microsoft 365 Groups from a user perspective. Groups are a central part of Microsoft 365 and their are several uses for it.
Click any header to get a detailed explaination.
Outlook
Group Calendar & Group Mail
Generates a group mailbox and a group calender. Both are found in Outlook.
Note!
If you create the group from Teams, this is hidden in Outlook. To unhide it you need to use PowerShell.
SharePoint
Files, Intranet & News
A SharePoint Team site is generated, this gives you access to Document Libraries and the News feature.
Every channel will be a folder in the Document Library. Privat channels will be SharePoint sub-sites and have their own Files and Intranet.
OneNote
Notes & Information
An OneNote is automatically generated it will be named “<teams name> Notebook”.
It’s stored in a Document Library call “Site Assets” in SharePoint.
If you create new OneNotes they will be stored in the folder they are created or the channel folder if created from Teams.
Planner
Tasks & Assignments
Is not generated, can be added later. If you create a Planner a M365 group will be created as well including everything above.
You can add more than one Planner to a M365 Group.
Teams
Communication & Collaboration
Teams is my recommended way of creating Groups for normal users. This hides the group from Outlook to avoid confusion.
