Hello, generally the person who creates the group is the group admin, but the admin authority can be transferred or replaced.

1. If the group is General Group, Secured Enterprise Group or a Cooperative Group, the group owner can transfer it by himself. If the group owner directly exits the group, the system will automatically select the next group member as the group owner;

2. If the group is All-hands Group, Department Group, the group ownership can be transferred by himself or withdrawal group to replace the ownership automatically by system, also super admin can also edit group admin in the OA management panel (oa.dingtalk.com) – “Contacts” – “Department”-“Modify” – “Group Admin” to change the admin of the selecting group.
