First of all thank you for reading my question. I've never used this software before. I have a database of about 37k in names and email addresses. I have a lot of duplicates. I would like to be able to find them and highlight them, So I could sort thru them and delete the wrong addresses. What is the best way to go about this? I tried performing a find with ! and it did not work. I'm thinking, maybe the problem is with the database? Its possible i didn't set it up correctly. Any advice would be appreciated.
