I have used this software for converting my emails into pst format so that i can migrate them as well as backup it without any hassle of loosing data again. There is nothing much bad about this program but sometimes when there's some problem while performing conversion then also if not solved properly after sometime your email will be converted with wrong settings causing loss of important information within few seconds only.. So try out first before using otherwise may lose valuable info. Migrating multiple mails at once instead doing one by one makes life easy!!
