MailsDaddy developed a very great product to convert multiple NSF files to PST. I feel very thankful for there work. MailsDaddy NSF to PST Converter is very helpful when anyone trying to access Lotus Notes Data in Outlook. It has some fantastic features. Preview can help you when you want to convert very huge data from NSF to PST. You can check important data and select it for importing into PST by using the preview feature. You can easily convert your NSF file data into EML, EMLx, MSG, HTML, MHTML, MBOX, VCF, CSV, ICS, and Office 365 & Live Exchange Server along with PST. I applied a date filter to convert important data only for specific time period. I am also using the MailsDaddy NSF to PST Converter for my needs, you also have to use the same.
