Office 365 Groups are a new way to collaborate within Office 365 through the use of group conversations, group calendars, Shared OneDrive, and an Email Distribution Group. Information Workers within an organization can easily create a public or private groups within a few seconds which makes them extremely convenient for ad-hoc requirements. Your users for example won’t need to liaise with IT or submit change requests in order to get shared calendars or somewhere to share content.
Users can create groups from within Outlook, People, OneDrive or Calendar.

Upon creating a group, you will be required to provide a name and description. It is possible that the name is already taken, and therefore you should choose another name.
Upon creation of the Office 365 Groups, you will be able to subscribe new members who will receive notification that they have been subscribed to the new group. You can then immediately begin to use the Group Conversations, Group Calendar, and OneDrive.
You can also edit the details of the group, although you won’t be able to change a group from Public to Private. Any Group that you created or have been subscribed to will display within Outlook, People, Calendar or OneDrive in the left hand Navigator under More. If you are not subscribed to a group, you can Search for Groups and Request to Join the Group.
Groups can be managed using the Admin page within Office 365. You will be able to view the email address provided to the group, as well as manage members or delete the group.
You may also use Powershell to manage Groups. A number of cmdlets can be found here: https://support.office.com/en-us/article/Use-PowerShell-to-manage-Office-365-Groups-aeb669aa-1770-4537-9de2-a82ac11b0540?ui=en-US&rs=en-US&ad=US

The Microsoft Graph endpoint also allows developers to use a single end point to obtain information about Groups. Using the Microsoft Graph API Explorer, you can query information on groups using https://graph.microsoft.com/beta/myorganization/groups
