Activating an account changes its status to Activated and allows a user to sign in. Conversely, deactivating an account changes its status to Deactivated and denies the user the privilege to sign in.
You can activate all members of a group at once. This activates any deactivated members of the group and all subgroups. You also can deactivate all members of a group with the same type of effect.
To activate or deactivate the members of a group
A user with a deactivated account has an icon that contains a red slash (). A user with an activated account does not have this red slash.
All users are activated or deactivated as needed.
