Outlook hangs on open

I have one Windows XP computer running Outlook 2002, and they seem to all of a sudden be having an issue where Outlook Hangs for about Two mins before opening. Something is obviously hanging it up…But I am not sure what!?? Its very frustrating for the user… Does anyone have any Idea’s? She is hooked up through our Network, through the patch panel and then to the hub. I even tried changing her port to another hub. Please help!
