I had to deal with this same issue trying to send Outlook email from Access. I used Outlook Redemption, a third-party COM library that wraps the calls to Outlook and avoids those annoying popups. It is free unless you want to redistribute it, in that case you would need to buy the redistributable version for $199.

How Outlook Redemption works

Redemption is a regular COM library;
once registered on the system, it is
accessible to any programming language
(VB, VBA, VC++, Delphi, etc).
Redemption uses Extended MAPI (which
is not affected by the Security Patch
since it is not accessible to the
scripting languages) to duplicate the
functionality blocked by the Security
Patch. All Safe*Item Redemption
objects have an Item property which
must be set to an Outlook item. Once
set, you can access any properties and
methods, both blocked and not blocked.
For the blocked properties and
functions, Redemption objects
completely bypass the Outlook object
model and behave exactly like Outlook
objects with no Security Patch
applied. For the properties and
methods not blocked by the Security
Patch, all calls are transparently
forwarded to the Outlook object that
you assign to the Item property. With
this approach changes to your code are
minimal: you only change the way you
declare the objects, but not the rest
of your code that actually accesses
both blocked and not blocked
properties and methods.
