Outlook 2007 + Exchange 2003 problem

[Jef]

When i setup outlook 2007 on our internal network everything works fine.
However when the user takes the computer to an external network Outlook 2007
does not work. It just says trying to connect and will never go to a
connected status. Once i delete the outlook profile and recreate it
everything works fine. We have had this same problem happen on about 5
different machines. All with outlook 2007, why is this happening?

How can i resolve this problem?

How is he trying to connect to the exchange server? RPC over HTTP or classic
Exchange?

It should be RPC over HTTP....We have hundreds of other users that are using
outlook 2003 & 2007 and it works great. So i dont think its a server
problem...

What about firewalls on the external network?
