I need to change the throttle policy on Exchange Server 2010

I have a client that has 10 workstations connected to a SBS 2011.  It is running exchange 2010.  They are all using Office 2003.  I know..... Most of these users do not like change and are on in their years and do not want to try anything new.  When the office manager has the Outlook calendar open automatically with 4 other partners in the office she begins to have connection problems in Outlook 2003.  I am trying to talk them into at least upgrading their Outlook 2010.  Everything I read on line says that this is a problem with Outlook 2003 and Exchange 2010.  Having that many calendars open causes a exchange throttle policy violation and basically says that hey have " run over budget"  The error code at the event viewer is 2915.  Is there an easy way to disable the throttle service?  I am good with regedit and modifying system parameters but the only thing I am finding as far as a fix is a Powershell command that has a syntax so long that it would choke a horse,  Is there not something in the exchange management that can be modified that might be GUI friendly?
