I have a similar problem after installing Office XP on a new laptop
with Windows Vista. Every time I start Outlook I get this message
once for every entry in my Contacts folder (several hundred times
until I deleted all of my contacts). The addin tool does not stop
this. It identified a "btosif.dll" as the culprit; this is apparently
a bluetooth application, which I have no idea how to disable. After
running the addin tool I can add a contact without getting the
message, but the next time I start Outlook I again get the message
for every entry in my contact list. I have no idea what to do at this
point.
