This is a much-requested feature - e.g. Right-click an appointment and Reply-All. Not sure if Apple have this as a feature request anywhere?

I agree that this is a very important feature that is missing.
As a workaround for invitations where you are the organizer, you can click in the "Invitees" edit field and copy/paste the email addresses.
It is still cumbersome, and does not work for invites where you are not the organizer, so we need this to become a feature in Mail.
