I suggest utilizing the Aryson NSF to PST Converter Tool to import Lotus Notes.NSF files into Outlook PST. With simplicity, this utility can convert NSF files to several different formats, including Outlook PST, EML, MBOX, MSG, PDF, and more. It makes it easier for contacts, calendars, emails, and other data to move from Lotus Notes to the Outlook client. Furthermore, one or more NSF files may be imported using this option by Office 365, Exchange Server, and other cloud-based email systems. Furthermore, it facilitates the export of emails from Lotus Notes (NSF) files to widely used email clients, such as Gmail, Yahoo, AOL Webmail accounts, and IMAP servers. Users are able to backup up to 50 things using the NSF to PST Converter Tool's free edition. A membership is required in order to utilize the program to its fullest.
