Outlook unable to connect to Exchange with http

I need the RPC over http to work.

Server: SBS Server 2003 with Exchange 2003. All service packs applied. Single server environment.
Client: Outlook 2007

Exchange is configured more or less "standard". Outlook clients works fine at LAN using TCP/IP.

We have bought a certificat for "webmail.domain.com", and use it for OWA.  Firewall redirect port 443 to the exchange server. The OWA works fine from outside, from inside the FQDN does not work (because of firewall config) but I can use OWA internally by entering the local servername in the browser (even if I have to accept the complain about the certificat then).

I have followed the instructions here: http://www.amset.info/exchange/rpc-http.asp

Outlook is configured while in the LAN. Then leaving office with the laptop, connect to internet, starting Outlook again it ask me for username/password.
Everything seems nice until this point because Outlook never goes online, just says "offline" in the lower right corner.

I am obv. doing something wrong, please help.

Best regards

I made a couple of reboots, checked all settings again (without really changing anything) and all of a sudden it works. The bad thing with this is that I really do not know why...   :-)

Mestha: Are you really sure that SBS Server 2003 have the feature from start? So next time I install a SBS server, all I have to do is:
1.  Enable it during the "Connect to internet"-wizard.
2. Buy a certificat and install it correctly.
3. Configure the firewall.

If this is right, after done nr 1 above, it should work with no problems on the LAN with http, is that right? That would be good to know for testing purposes in the future.

Thanks for your help.
