Hey, I'm trying to modify a mail item, but for some reason it gives me a success status code, and a modify date, but I see no different when updating the inbox...

Here's the XML...

Code:
<SOAP-ENV:Envelope xmlns:ns0="http://schemas.novell.com/2005/01/GroupWise/types" xmlns:ns1="http://schemas.novell.com/2005/01/GroupWise/methods" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:tns="http://schemas.novell.com/2005/01/GroupWise/types" xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/">
   <SOAP-ENV:Header>
      <tns:session>4OvSpD1dYNKJ8zkb</tns:session>
   </SOAP-ENV:Header>
   <SOAP-ENV:Body>
      <ns1:modifyItemRequest>

                  </ns0:sendoptions>
               </ns0:distribution>
            </ns0:update>
         </updates>

</SOAP-ENV:Envelope>
