The Holywood man entered the final round of the tournament two shots off leader Stephen Gallacher.
The Scot hit an even par round to win the tournament on 16 under.
It is the first time in the competition's history the defending champion has retained the title.
A disappointing round of four bogies and two birdies saw Rory finish the tournament on 12 under, four shots off the top spot and tied in ninth place overall.
A poor start from Gallacher meant McIlroy's opening six pars were enough for him to take the lead, something the former world number one was unable to build on.
At the seventh, he dumped his tee shot in the water, just short of the green.
Although he rescued a bogey with a brilliant third shot from the drop zone, McIlroy never reproduced the form which saw him shoot an opening 63 in the competition.
McIlroy is due to play again in the World Matchplay Championships in just over two weeks' time.
