One should always go for superior stuff in all parameters. Hence I would recommend an award-winning tool like eSoftTools NSF to PST converter to migrate from Lotus Notes to Outlook. Even this tool has the ability to export NSF files into 9 different file formats which include options such as- EML, EMLX, HTML, MSG, vCard, PST, etc. Also, the PST file can be divided into many PST files through its split feature. A free demo version is also offered to all users to access this software without paying money.
