I have one user (Vista Business, Outlook 2007 connected to Exchange 2003) who
has today started to see a pop-up from Outlook saying:

"A program is trying to access e-mail address information stored in
Outlook. If this is unexpected, click Deny and verify your antivirus
software is up-to-date."

Anti-virus (McAfee) is up todate, and I'm doing a scan now and afterwards
will do a separate scan for malware. This user tells me that he hasn't
knowingly installed anything recently.

My question is: is there any way to determine what the program is which is
trying to access e-mail address information stored in outlook?

This is a sign of an add-in that wasn't written correctly. Here are your
options with respect to the Outlook Object Model Guard:

This tool, also mentioned on the page I just cited, is supposed to be able to
help pinpoint the aapplication: http://www.mapilab.com/outlook/security/
