Pascal,
when I'm in the office I am on the same network of Exchange server using network 10.10.130.x/255.255.255.0
Server Name is called ERBOEX and reply on IP 10.10.130.13. I connect to the server using server name. This exchange server is not visible on the internet. To get/send email from internet we use a DMZ email server just as email transponder.
When I go home, I connect to internet using an ADSL line at 640kb and I get a dynamic pubblic IP. Then I run Wingate VPN and connect to office VPN.
From now on I can connect to shared folders on my office servers without any problem, I can ping Exchange server, so in general all seems working fine.
Then I run OutLook (in native Exchange connection) and I'm able to connect to Exchange server without changing anything in my config, so ERBOEX as Exchange server name. I can connect correctly and see all my mail folders and all the mails.
Problem starts when I double click on any mail. Outlook waits and after some time gives "Insufficient memory to perform the operation" than hangs.
In the meantime I discovered this Microsoft link showing all the ports used by Exchange Server
http://support.microsoft.com/default.as ... bContent=1
I will double check again my firewall to see if some IMAP config is missing.
Thanks a lot
Eros
