Context: Jets and outflows are key ingredients in the formation of starsacross the mass spectrum. In clustered regions, understanding powering sourcesand outflow components poses a significant problem. Aims: To understand thedynamics in the outflow(s) from a cluster in the process of forming massivestars. Methods: We use new VLA observations of the molecular gas (SiO, CS, OCSand \molec) in the massive star forming region IRAS 17233-3606 which contains anumber of HII regions. We compare these observations to previously publishedmolecular data for this source in order to get a holistic view of the outflowdynamics. Results:We find that the dynamics of the various species can beexplained by a single large scale ($\sim 0.15$ pc) outflow when compared to thesizes of the HII regions, with the different morphologies of the blue and redoutflow components explained with respect to the morphology of the surroundingenvelope. We further find that the direction of the velocity gradients seen inOCS and \molec are suggestive of a combination of rotation and outflow motionsin the warm gas surrounding the HII regions near the base of the large scaleoutflow. Conclusions: Our results show that the massive protostars formingwithin this region appear to be contributing to a single outflow on largescales. This single large scale outflow is traced by a number of differentspecies as the outflow interacts with its surroundings. On the small scales,there appear to be multiple mechanisms contributing to the dynamics which couldbe a combination of either a small scale outflow or rotation with the dynamicsof the large scale outflow.
