Stop the program that asking to permit to send the email

I currently have to send an email to around 500 clients using Outlook 2002 which is the company’s default emailing program. However, I have a problem that persists during sending of the messages. The database program we are using keeps asking me whether I would like to permit it to send the email. Can you imagine having to do this for each and every email? That is around 500 times which is very annoying not to mention the amount of time spent doing it. Does anyone have an idea how to stop this madness?
