Internet access to Exchange server for Outlook

Hi All,

I just picked up responsibility for a sbs 2003 server running
Exchange.

Now on one issue, I am completely puzzled.  On a number of
laptops, the customer has Outlook installed and working
with the exchange server.  They all work perfectly inside
the local network.

Here is what is puzzling.  One of the laptops Outlook works
outside the network (over the Internet).  And it
is not Terminal Services.  When this laptop is
inside the LAN, Outlook just pops right into Outlook.
When this laptop is outside the LAN (from the Internet),
He gets a username and password prompt to log in.  Then
he is attached to the Exchange server as if he was on the
LAN.

The rest of the laptops will not connect over the Internet.
The customer wants me to configure them all for
Internet access to Exchange.

I have looked at the Outlook configure pages and they
are all identical.  For the server, they all reference the
internal LAN (acme.local) domain name, not the Internet
domain name.

What in the world?  My brain hurts!

Many thanks,
-T

Google up on that, check out the laptop that will work and then
implement that across the board if you need.

Are you sure this is a live connection, and not just using cache mode?

Are you sure this is a live connection, and not just using cache mode? Does
he receive an email OK and is able to send a new one (and it is received). I
always thought you had to use OWA if outside, unless you are making a VPN
connection.

Hi Phil,

No VPN or Terminal Services.  He receives everything live.
