Well, you'll most likely have to get with the people that wrote that component. If you purchased it, then you have at least 1 FREE support incident, otherwise it's $159/incident. If the IP works in Outlook, the exact same server name/IP should work in this component. If it's not, there might be some setting in this component that you have to set, but have so far failed to do so. I have no idea what that would be, since I've never used this component. Another possibility is that you have the free version and it expires. If so, then you'll have to shovel out the money to get the full version.
