Hi Brian - It took me some time to find how to mark contacts as
private but in the end I found it and some of them were indeed marked
private. That seems to have fixed it - thanks!

You're welcome. I'm not sure why you found it difficult to locate, since
it's right on the Contact form.

Seeing as I didn't even know where this feature was, I am baffled as
to how they got marked private in the first place. Any thoughts? Is
this a default that I can switch?

Programmatically I think it can be done, but that's outside of my
familiarity with Outlook.
