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: This utility is easy to use and free. The
website provides code to use to turn the utility on and turn it off when
done. I use it.]
"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
For Outlook 2003, Sue also advises:
"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"
