For the life of me, I can't get this to work:

<cfset username = "domain\username">

<cfset password = "password">

<cfset server = "exchangeserver">

<cfset mailboxname = "firstname.lastname">

<cfexchangeconnection action="OPEN" connection="conn1" server="#variables.server#" username="#variables.username#" mailboxname="#variables.mailboxname#" password="#variables.password#" protocol="https" serverversion="2010" formbasedauthentication="True" formBasedAuthenticationURL="https://#variables.server#/owa/auth/owaauth.dll">

I know the URL is correct, because if I go to https://exchangeserver/owa/auth/logon.aspx, I get to the web login page.

My error:

What the heck am I doing wrong?  The earlier error I got was a certificate error, which I resolved using keytool and cert.  We are using Exchange 2010.  I did find this:

ColdFusion Connecting to Exchange 2010

So is this a bug?  If so, does it still exist in CF11?  Thank you.
