New contacts are automatically assigned to the specified standard contact groups either as soon as they are created (when you click the New button), or they are imported as a vCard or from the call data list. However, contacts that have been created by importing an address book file are not automatically assigned to a standard contact group.

You can define one or more contact group(s) as your standard contact group. If you are logged on as a user, you must define at least one contact group as your standard contact group before you can create a contact. This is because users cannot create a contact without a contact group.

A Google contact group cannot be used as standard contact group.
