Mail through VPN

[Dominik]

Hi,

When I try to connect my business mail (which is under Exchange) via VPN
with Outlook 2003 sp2, I receive the message
"error (0x8004011D) : 'The server is not available. Contact your
administrator if this condition persists."
On another hand, I can access via VPN to others ressources and even to our
Intranet. So the problem seems to be limited to mail access.

Did anyone meet and resolve such a trouble ?

Thanks in advance.
