Found some old post as well from 2007:
http://www.linuxquestions.org/questions/linux-software-2/evolution-exchange-and-active-directory-authentication-582014/

URL: https://staffnet.example.com/OWA/
Works in the browser.
Tried: /exchange /owa /OWA
When typed wrong password, definitely there is different message, so it recognise the password.

CORRECT PASSWORD ERROR:
"

Could not configure Exchange account because
an unknown error occurred. Check the URL,
username and password, and try again.
"

WRONG PASSWORD ERROR:
"Could not authenticate to server.

This probably means that your server requires
you to specify the Windows domain name
as part of your username (eg, "DOMAIN\user").

Also, you may have typed your password incorrectly."
