I have big trouble with outlook 2003 or 2007 that want to communicate with exchange 2003 over VPN. I have read many pages about it on internet and also on EE but noone leads me to solve my problem.
Mabye I found one diference than is described in other problems of "0x8004011D": we use fortinet products for making VPN connection. And problem is on clients side which use forticlient IPSec or SSL VPN tunel. If the client gets IP address from VPN DHCP server connection between client's outlook and exchange isnt estabilished. But if I set IP address manualy to out of range of VPN DHCP the connection is estabilished but only once. If I close outlook and disconnet VPN connection and connect client to VPN again with the same manual IP address Outlook doesnt connect with exchange.
On client side I can always ping the exchange server its IP or domain name. There is no firewall activated on client side, router, exchange. Exchange on local network works correctly. OWA works correctly.
I tried reset or flash with newest firmware the router but without effect.
Thank you for your help.
