Can anyone tell me whats wrong. The error I keep getting is "Access to the Exchange server denied. Ensure that the user name and password are correct."

I've done all of this.
adobe.com
Code CFM:
<cfexchangeConnection
action="open"
connection="sample"
server="mailserver"
protocol="https"
username="username"
password="pasword"
formbasedauthentication="true"
formBasedAuthenticationURL="https://webaddress.com"
/>
 
    <cfexchangecalendar action="get" name="mycal" connection="sample">
        <cfexchangefilter name="startTime" from="#theDate#" to="#theEndDate#">
    </cfexchangecalendar>
 
<cfexchangeConnection action="close" connection="sample" />
