Unless you have 25k more data in the problem contacts than in the "good" contacts, the symptoms suggest that the problem contacts are using a one-off form. That also fits with the other symptoms.
The easiest solution may be to update your copy of Outlook. I presume it is Outlook 2000, but that you have not applied Office Service Pack 2. That means you are working with a pretty old version that is not very secure.

I really don't know the answer to your questions, because you haven't provided any context for your scenario. Please tell us about it in more detail

You have a couple of choices. You can either keep them in separate folders since these classifications presumably don't overlap. Or you could keep them in the same folder, but use two different categories to distinguish the two types of items.

>> The symptoms certainly indicate that the items in question were created with a custom form that was not published in any of the forms libraries. "Macro" is a red herring. The message refers to VBScript code behind the custom form. A useful diagnostic might be to add the Size property to the current folder view and compare the size of the items that trigger this prompt with other items that don't.
