How can I tell what program is accessing Outlook address book?

[wease2u]

Each time I click on the "New" button to create a new e-mail message, a
window pops up with a message informing me "a program is attempting to access
contact list." What program? Should I be concerned about this? What can I
do to stop this message from appearing? Thanks for any help you can give me.

These prompts are from the Outlook Email Security Updates contained in
all current versions of Outlook and in all Service Packs after SP1 for
Outlook 2000. These updates add additional actions to the list of those
that are blocked from accessing the Outlook Address Book. Antivirus and
antispam add-ins are a common cause and others may be affected as well
(for example, Adobe Acrobat's Outlook addin called PDFMaker is a very
common one). As a result, one of the add-ins or programs you are using
that access your Outlook Address Book needs to be updated. Many add-ins
were updated following the release of Outlook 2003 and should work. If
not you'll need to contact the vendor for a newer version.

http://www.slipstick.com/outlook/ol2002sp3.htm#problems has a list of
applications known to trigger the security prompt.
