Not sure if this can work or not, but it's worth a try. I'm trying to use Outlook with an IMAP/POP email account (not exchange) and everything works well when I am at the site. However, go away from the site and connect via VPN (Sonicwall TZ170 at the site and Global Vpn client running on the users PC) I can't get connected to desktop messaging. Opened more ports than I can remember based on various searches, to no avail. At this point the user can log into Outlook from the tunnel, but never get the Callpilot splash screen and the user can only see email messages. Can this/ should this work. Any ideas would be greatly appreciated.
