How to get member of Office 365 group in SharePoint Online?

Question

I have created user group Group-1 in SharePoint Online Site. I have added few members in Group-1.

Now, I have created a group Group-2 in Office 365 and added few members in the Group-2. Now I have added this Group-2 in SharePoint Site.

Now when I am trying to get the Groups and Members of SharePoint Site then I am getting only Groups created in SharePoint, but I am not getting the group created in Office 365 and associated in SharePoint.

Note: I am able to see that Group-2 in SharePoint using GUI but not members.

Question:

How can I get the Group-2 and its Members in SharePoint programmatically?

Let me know if there is need of more details.

Answer 2

Did you create an O365 group in Office 365 Admin Center directly? If yes, you need to add members to the Group-2 in SharePoint site manually.

Answer 3

In That case it should added to any other group as a member. as in given screen shot I have shared site with "Test Group" which is office 365 group and it is added to Member Group of sharepoint site group.
