I am trying to use Outlook Web Access to get to my e-mail. It is an Exchange 2000 server running Windows 2000 server and uses Active Directory. Everything works perfectly fine when I access OWA from within my local domain. However, from any machine external to the domain it behaves consistently erratic. I can list the inbox messages but when I try to read a message I get an HTTP 400 (Bad Request) error. I can list the public folders, however only half I can open and read while the other half get the same HTTP 400 (Bad Request) error. The symptoms are the same with either IE or Netscape browsers.
