CFExchange and Attachment Issue

Question

Hi,
I'm working on getting attachment from a message, but each time it throws 501 error message. I'm following the documentation on attachments, but the code doesnt work for me. I searched this forum as well as google. Others, having the same issue with no solution posted.
Here is the code:
    <cfif mailMessage.hasAttachment>
     <cfset i = 1>
     <cfset path = "#GetDirectoryFromPath(ExpandPath('*.*'))#attachments">
        <cfdump var="#path#\#i#">
        <cfloop query="mailMessage">
            <cfexchangemail action="getAttachments" connection="checkMail" folder="#session.folder#" uid="#url.id#" name="attachment"
                attachmentPath="#path#/#i#" >
            <cfset i++>
        </cfloop>
        <cfdump var="#attachment#">
    </cfif>
Any suggestions?

I can connect to exchange server successfully, get emails etc. So,  added the above code to get attachments (when there is an attachment for an email).
It happens on all the message that has attachments. Messages without attachment works fine.
Exact error code:
Exchange error Code : 501.
Exact message
Error performing the action.

Line 24 is:
<cfexchangemail action="getAttachments" connection="checkMail" folder="#session.folder#" uid="#url.id#" name="attachment"
                attachmentPath="#path#/#i#" >
