When trying to use OWA (Outlook Web Access) from outside the local area network in which the server resides, it does not seem to load stylesheets, images etc, just plain text, and no Inbox.
When using OWA from inside the local area network, it loads just fine.
We have tried to forward/map all the ports that Exchange/OWA need, referring to the Microsoft KB.
Also, we have tried it from multiple locations, so it is not a browser issue.
OS: Windows 2003 SBS Server SP2
Browsers: IE6, IE7.
