how to prevent outlook security dialog box from displaying

[Rajendra]

Hi,
I wrote Outlook COM Add-in which uses MAPI to access the
contact addresses using the "Contact Folder" item stored
on Exchange Server. when i try to access these contacts i
am getting Outlook security dialog box. what should i do
to prevent this dialog box from coming. I would like to do
it programmatically.

Environment:
Exchange Server as Mail server
POSTFIX as Mail Server
Outlook as Mail client

Thanks and Regards,
Rajendra
