(error 550 7 unable to relay)the solution provived by microsoft did not work and i did set the server to relay authenticated users regardless of domain. any help would be appreciated.

Most likely the problem they are having is that their ISP is blocking port 25 on their network and they will not be able to send messages through your server unless you alter the port that is used for smtp mail which you can change in exchange if I am not mistaken. If I can be of any further assistance please contact my company at support@meganetcomputers.com or visit my web site and leave a feed back form for us so someone can get back to you as soon as possible.
