Removing Group Level Admins

To remove Group Level Admins:

1. In the top navigation, click Users.
2. Select the Group administration tab. 
   A list of current group administrators is displayed. The list does not include groups from uncached Connector directories, Custom directories, and Azure AD directories which cannot be administered by Group Level Admins.
3. Remove a Group Level Admin by clicking the X button next to their name.  
   Remember that group administration rights can be removed from both users as well as groups so you can save yourself some time selecting multiple users and select the whole group instead.
