Meeting Creation and Tracking
I've seen this sort of thing happen when attendees use the attendee chooses the option to accept or decline "with no response." Have you checked to make sure that isn't the problem?
I had my suspicions about that issue, but it hasn't fully panned out. There is definitely a change of behavior based on the "Require Response" setting, but there are also oddities.
As far as I can tell, there is no way to set "require response" when creating a meeting from the group calendar. The little gear icon that controls that setting in the UI is not present during creation, but is present after the meeting has been initially saved. You can then edit that setting to require responses, but in my testing, I then only see the members who have responded and not the No Response invitees. I still believe that that is inconsistent with the documented behavior.
