I just installed Thunderbird 24.0.1 and imported my email from Outlook Express, but when I connected to AT&T Mail Server, all 13,000+ emails that I keep on that server downloaded into my inbox again... This tool quickly and effectively deleted the duplicates without issue.Seems to work just fine for me.P.S. I made a change to my Thunderbird and had to do this 2 more times because I found I had duplicate profiles/email accounts in my Thunderbird list of email accounts. Very pleased with this product and highly recommend it.
