Review on 4n6 Kerio converter by Bret Wong

I have been working with this program for almost two years now. It has been very easy to use and it has a great user interface. It works for both MacOS and Windows OS. It is compatible with many email clients. The only thing that I dislike about this product is that sometimes when you try to delete an attachment or a folder, it will not let you do so. Sometimes when I have to open my sent items, I have to re-download them again since they are already deleted. I would like to say, though, that this is not always the case. If your computer gets slow, this program will help you solve that problem. I am using it as part of my business. It helps me keep track of all my emails and files.
