Trying to Carbon Copy (CC) or Blind Carbon Copy (BCC) someone in an Outlook Meeting request can be frustrating because there is no obvious way to do it. However, you can do so by adding the person as either an Optional or Resource attendee to the meeting request.
Whomever you add as a Resource attendee receives the meeting request and can accept or decline, but other people you invite to the meeting do not see that person on the list of attendees.
1) In the meeting request, click the To... button.
2) In the Select Attendees and Resources window, enter addresses in the Optional box that you would like to CC and enter addresses in the Optional box that you would like to BCC.
3) Finish filling out the Meeting Request as you normally would, and click Send .
