I bought your Duplicates Remover for Outlook some time back and it worked as advertised - I had numerous archives to recover and it made a difficult job easy. Some time later I needed to repeat a similar process this time using the Systools product as I thought it would preserve the folder structure. What a mistake from bad customer service, to defending an extremely slow product that missed duplicates your product detected. Talk about an opportunity to learn the difference between creating a corporate enemy or a raving fan. Well Mapilabs know the difference and Systools don't. 10 out of 10 Mapilabs. All the best with your success.
