thats what i was going to say, you could try downloading an older version of Activesync, not too old tho. maybe 3.x or something like that. to download different activesyncs, i believe you can go to
www.UTstarcom.com or do a google search for Activesync. actually you might want to go to
www.microsoft.com and do a search for Activesync on there, they have all that archived.
hope this helps
