Managing Official Group Membership
Members are automatically added to Official Groups that are created via group directory sync, and you can specify members when you create Official Groups manually. Additionally, you can add and remove members of Official Groups at any time. If you have the Organization Admin role, you have rights to add or remove members of any Official Group in your Organization. If you have the Team Admin or Broadcaster role, you can add or remove members of only the Official Groups over which you have admin rights.
You can add or remove members of Official Groups on the Official Groups tab or on User Profile pages.

◦ To remove members, to the left of the User column, select one or more check boxes for the members you want to remove, and then click Remove Members.
