Mike,
Outlook users operating outside of the Exchange environment cannot turn this
prompt off. There are a few options available, as outlined by Outlook MVP
Sue Mosher:
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."
I have used the ClickYes utility successfully for myself and for a client,
using code provided by ClickYes which turns the utility on just before
sending the emails and turns it off when the process has completed. It
does not get rid of the prompt, but it uses code to click the 'Yes' button
for you.
hth,
