Query Exchange 2003 for valid SMTP AddressI am writing an application that needs to email to specific users on our
Exchange server and need to query it to see if the SMTP address I will be sending to exists. The application will be running on the same server as the Exchange Server. Environment is W2003 SP2 Exchange 2003 SP1. Allowing the email to bounce is not an option. Thanks in Advance, Mike Ober. "Michael D.
