Cleared for takeoff Runway XX. At 25 KTS received an 'on taxiway' alert. Rejected. Complied with QRH and waited 21 minutes and departed. At a higher speed the alert happened again but takeoff was continued.  While running RTO checklist we received an ACARS message for employee X to report to flight operations immediately on arrival. We called about the message and were told; 'Everything will be explained when we land.'  Due to elderly parents and sick family members; the crew member was distracted throughout the flight. Captain flew the leg and flight safety suffered due to our concern for what might be wrong.  Strange to get this message during departure ground operations.  Major distraction during a rejected takeoff. I suggest fix database; and add 'collection site' to radio call or the ACARS message so we don't think something bad has happened to our family members.
The Reporter stated that this aircraft had RAAS installed and because the departure runway had an overrun usable for takeoff but not landing; when he attempted to takeoff from the overrun area the RAAS interpreted the aircraft to not be on the runway. This event occurred on the second takeoff but it was ignored and the takeoff completed. This particular RAAS volume did not interfere with ATC radio or inter-cockpit communications. The reporter also added that the ACARS message from the Company after the reject affected both pilots even though it was addressed to the First Officer who had an ailing parent. Those types of messages should be delivered to the crew only after they are in a situation where stress and worry will not interfere with safety of flight duties.
An aircraft with RAAS alerted ON TAXIWAY during takeoff on a runway overrun suitable for takeoff; but not landing so the Captain initiated a slow speed reject but ignored the warning on the subsequent takeoff.
