Weird 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?

Hard to say. Which method of off-site connecting do you use? RPC over HTTP,
VPN, other?

RPC over HTTP is the method. We have hundreds of users using Outlook 2003 &
2007 and it works great. So i didnt think it was the server

So what exactly is the issue that needs to be solved? Sounds like you have
determined already that it is a corrupt mail profile which needs to be
recreated. Or does the problem re-occur for those machines after you
recreated the mail profile?

I am wondering why the profile works fine in the office and when you go
outside the network it doesn't work. However if you bring the computer back
in the network it will work. What information is saved in the profile to
cause this problem?
