If you have received the following error message "You already have a meeting request (or confirmation) with [[the attendee's name]]", that means you have previously submitted a meeting request to that attendee.  You will not be able to submit a new meeting request until the original one was accepted, declined or canceled.

If you received an error message stating that your meeting availability has not been set, please set your meeting availability and try again. You will not be able to request meetings or respond to meeting requests until you have set your meeting availability.
