Hi, I have code for sending batch emails to addresses listed in a query, which works fine on my pc with outlook express, but with outlook on the client's machine it keeps getting that pesky security message for every e-mail it tries to send. the client however also has outlook express installed, its just that outlook is automatically used. how do you force access to use outlook express instead? does it have to be configured to be the default mail client? any help is much appreciated. thanks!
