I have installed configured Exchange 2007 on Windows 2008. I can access it via Outlook from the same subnet, but I have a Class B network /16 and would like all of my subnets to be able to use Outlook. How can I configure that w/out using Outlook anywhere?Thanks-TroyMaybe my questions is better asked this way, "How can I configure WAN access to Exchange 2007?"

Troy, If the B class network is an internal network you should check your router/layer 3 switches if they contain the right routes. Then if that is ok try to ping the Exchange server and look if that works. Johan

I think I jumped to a conclusion. So far I was the only user (on same subnet as server). When I added another user (not on same subnet) he got "Unable to contact Exchange Server Make sure it is online". He is using Windows Vista/Outlook 2007 (as am I). But I just took my laptop to another subnet and it was able to connect fine. Ideas on troubleshooting that?
