Questions regarding the Outlook Security prompt are asked very frequently.
The most complete answer has been provided by Outlook MVP Sue Mosher and is
as follows:
BEGIN QUOTED MATERIAL:
"The security dialogs that pop up when an application tries to access
certain Outlook properties and methods are designed to inhibit the spread of
viruses via Outlook; see
http://www.slipstick.com/outlook/esecup.htm#autosec. If you are a standalone
user, Outlook provides no way to suppress this behavior. However, you can
use a free tool called Express ClickYes:
(
http://www.express-soft.com/mailmate/clickyes.html)
to click the security dialog buttons automatically. Beware that this means
if a virus tries to send mail using Outlook or gain access to your address
book, it will succeed.
[Note from Cheryl: the writers of Express ClickYes have provided free code
at their website that you can use to turn the utility on when you need to
send an email from your application and then turn it off when your email has
been sent.]
"If you're the administrator in an Exchange Server environment, you can
reduce the impact of the security prompts with administrative tools. See
http://www.slipstick.com/outlook/esecup/admin.htm
"If it's an application you wrote yourself, you can use one of these
approaches to redo the program:
-- Use Extended MAPI (see
http://www.slipstick.com/dev/mapi.htm) and C++
or Delphi; this is the most secure method and the only one that Microsoft
recommendeds.
-- Use Redemption (
http://www.dimastr.com/redemption/), a third-party
COM library that wraps around Extended MAPI but parallels the Outlook Object
Model
-- Use SendKeys to "click" the buttons on the security dialogs that your
application may trigger. See
http://www.slipstick.com/outlook/esecup.htm#autosec for a link to sample
code.
-- Program the free Express ClickYes
(
http://www.express-soft.com/mailmate/clickyes.html) tool to start suspended
and turn it on only when your program needs to have the buttons clicked
automatically."

END OF QUOTED MATERIAL
In a recent post in one of the Outlook news groups, Sue Mosher indicated:
" ... Outlook 2003 does not show security prompts on three specific types of
applications:
-- VBScript code in published, non-oneoff Outlook forms
-- Outlook VBA code that uses the intrinsic Application object
-- Outlook COM add-ins properly constructed to derive all objects from
the Application object passed by the OnConnection event"
