Error Outlook 2007 Distribution Lists

Using Outlook 2007 w/ Windows 7.

I have manually created five distribution lists from scratch for company public use. When I click on any contact in that distribution list, I get an error message that states Outlook "could not find Contact "[contact name and email address]". It may have been deleted or moved from its original location. Would you like to remove it from this list?" Obviously the answer is no. When I choose no, the contact is still there, but descriptive information ex. business title, is gone.

This only occurs on other user accounts. I cannot recreate the error on my own Outlook.

Can you tell me what might cause this problem and how I can fix it?

Updating did NOT work. Tried that one already.

Thanks,

Amanda
