'Delete Spam Messages' not working - Endpoint Protection Suite Plus

Hello all,

I am running Endpoint Protection Suite Plus on SBS 2011 with Exchange 2010.

I am having issues with the Antispam settings. I go to settings and put a check in the box next to ‘Delete Spam Messages’. I press ok and exit the program. When I open the program back up and go back to Antispam settings the box next to ‘Delete Spam Messages’ is unchecked again. The Antispam module is scanning and flagging spam messages no problem. Its just the delete feature I seem to be having trouble with. Any help would be much appreciated. Thanks!
