I seem to have this type of problem too:

• I have Outlook 2003, connected to an Exchange2000 server, with no particular policy set concerning add-ins.
• I don't experience the problem when retrieving items, but when moving them programatically (i have a "To Visit" folder, which I clean up periodically).
• My News Folder goes to it's own .PST
• I have a small macro that basically does:

For Each objNote In targetFolder.Items
(...)
objNote.Move savFolder
Next

• Whenever it launches, I get a message saying "an application is trying to access your adress-book, allow access for" and a drop-down box, from which I can pick times (I usually select 2 minutes), It seems that there's no way to set this programatically.
