Sending Outlook email pop up box

I have code that sends an email when a certain cell has a value. Once the code begins a Microsofy pop up box appears prompting the user that a VBA application is trying to send an email. Do you want to proceed? My question is how do I prevent the box from appearing and just send the email?
