Do I understand correctly, if I upgrade from Outlook 2007 to outlook 2010, I would be able to have more rules allowed on my workstation, which is connected to a small business server 2008 using exchange 2007? In other words, how do I expand the rule functionality on XP pro workstation connected to the exchange server so I am not be limited by my outlook 2007 rules? It says that I am out of space. What do I have to click on and which computer do I click on it. Where do I go in exchange 2007 on small business server 2008, within the core store, to expand the public and personal folder rule limitations?
