Outlook Anywhere Connection Problem

[Michael]

I'm getting the error "The action cannot be completed. The connection to
Microsoft Exchange is unavailable. Outlook must be online or connected to
complete this action." when attempting to setup Outlook Anywhere (2007/SP2)
to my Exchange 2007/SP1 Server. These Outlook clients are on a non-domain
external systems. I'm using a single certificate from a third party CA
(thawte) with Autodiscover redirection.

The error occurs during setting up the Outlook Anywhere profile. I enter
the user name, e-mail address, and password and am prompted "Allow this
website to configure (e-mail address removed) server settings?" with the following URL
displayed: https://external.domain.com/autodiscover/autodiscover.xml (my
external Exchange server name). I select "Allow" and the profile setup
continues to "Search for (e-mail address removed) server settings" and errors before
getting to "Log on to server."

Here is a system configuration summary:

1) OWA functions as expected using https://external.domain.com/owa (this is
my external name). Certificate is valid.
2) RPC or HTTP proxy installed. Exchange on 2008 server.
3) External URLs for OAB, ActiveSync, OWA set to
https://external.domain.com/...
4) External host name for Outlook Anywhere set to external.domain.com in
Exchange
5) Autodiscover redirection seems to work. Browsing to
http://autodiscover.domain.com/autodiscover/autodiscover.xml prompts for
domain account info with external.domain.com in the title bar of the account
dialog. After providing domain account info, the XML page is displayed.
Certificate is valid.
6) Using Outlook's Test E-mail Autoconfiguration succeeds indicating the
autodiscover redirection is used after failing to find
https://domain.com/autodiscover/autodiscover.xml and
https://autodiscover.domain.com/autodiscover/autodiscover.xml. The process
prompts me for a user name and password and the dialog contains the internal
name of the server in the title bar. Supplying the correct domain account
allows the autoconfiguration test to succeed.
7) http://support.microsoft.com/default.aspx/kb/927481 doesn't seem to apply
because ZeroConfigExchange is not present in the registry.

Any help would be appreciated.

Does it work if you manually configure the account? Have you tried the
