Calling web service from Outlook

[KathyB]

I have a customer with an Outlook Add-In installed that consumes a web
service hosted on our server. When she copies and pastes the URL to the asmx
page in her browser, the asmx page renders fine. When she attempts to use the
add-in through Outlook, she gets this message: The remote server returned an
error: (514) Web Acceleration Client Error (514) - Proxied HTTPS Request Not
Supported.

The Outlook Add-In works fine from another computer in the same office.

Any ideas? Thanks!

What version of Outlook and IE on each machine? Same OS?

Is one machine using IE6 and the other one IE7? Are both versions of Outlook
the same?

Using the IE clipboard with code will produce warnings and errors with IE7,
where the same thing works with IE6.

Both systems are Windows XP with Outlook 2003. Both browsers are IE6.

To clarify:

System 1: Can browse to web service but Outlook Add-In's call to web service
generates the error.

System 2: Can both browse to web service and consume web service from the
Outlook Add-In

Then you're going to have to look more closely as to what the differences
are between the two systems.

Should I start with security settings, conflicting software, conflicting
hardware, their ISP, or something else? Or could it be any one of these
things?

It could be any of those things plus A-V software, script stoppers, you name
it. There's just no way to tell offhand if the easy things are eliminated.
