The best feature is that it can convert many email attachments in one go, which makes my work easy.
I don't like anything about this software! It's not user friendly at all, so if you are looking for an efficient tool then avoid using jageware eml-nsf wizard because of its complicated interface; moreover there isn't any customer support service as well from them when we have issues while working, they just ignore us or make fun of our problems without giving help even after paying their fees. If your emails contain large number of attachment than use jag ware mail converter otherwise i would suggest avoiding using this product entirely, also try out other free products available online instead of wasting money by buying such useless stuffs. This program helps me to reduce size of file by converting outlook emails to nsf format along with.
