You can avoid this happening by downloading the "Express ClickYes" utility
that is available as a free download from:
http://www.contextmagic.com/express-clickyes/
Express ClickYes is a tiny program that sits in the taskbar and clicks the
Yes button on behalf of you, when Outlook's Security Guard opens prompt
dialog saying that a program is trying to send an email with Outlook or
access its address book. You can suspend/resume it by double-clicking its
taskbar icon. Developers can automate its behaviour by sending special
messages.
