VPN and Outlook conflicts

[DiLauro]

I have some basic questions about how VPN and Outlook work together. The setup is: Windows XP SP2, Outlook 2003 through DSL connection. In addition, I have an VPN network that uses the same OUTLOOK. So I have multiple email account in OUTLOOK, no problem.
Recently, our ISP provider told us to change server names (sbcglobal to att) and to move over to SSL ports for both pop3 and smtp. As long as the VPN is up and running, I can not pass the tests with SSL. When I take down VPN everything works fine. Checking the VPN setup, I could not see any ports defined.
I've also noticed that If I exit OUTLOOK normally, it appears down, but the VPN Outlook connection remains and really OUTLOOK is still up and running. Next time I will have to look at the task manager to see how many OUTLOOKS are running.

But the basic question is how much can VPN's that connect to OUTLOOK conflict with your other normal DSL ISP connections

I've done some testing with different VPN's
I can startup and run an IBM VPN and configure my OUTLOOK for SSL ports (incoming/outgoing) and the connection is fine and the test email is sent.
I then, shutdown IBM VPN and start up CBS' VPN. This time when I configure OUTLOOK to use SSL ports, the connection fails and no test email is sent. As soon as I disconnect the CBS VPN,
I can use the SSL ports. I've looked at the CBS VPN configuration (at least what the client sees) and other than Proxy settings, there is not much in terms of what ports can and can not be used.
I've made sure that all of this is the same With and without any Firewall actie

Sounds like a firewall issue with whatever site you are VPN-ing into (CBS firewall)
