Google’s customers have frequently requested the ability to restore recently deleted users. Starting today, admins can do so in the control panel. The process will recover most if not all data.
– You must have super administrator privileges.
– You can only restore users that have been deleted in the past five days.
– The deleted user name must not match an existing group name or another active user’s email address or alias. If it does, you’ll see a ‘username already exists’ error message.
– You can’t exceed your maximum number of user licenses. If you try to restore a deleted user when you don’t have an available license, you’ll see a ‘domain is over user limit’ error message.
– The option to undelete users is only visible in the top-level organization even if the deleted user was in a sub organization.
