Lotus Notes NSF Export to PST - Version 9.3 By exchanging NSF to PST, you can migrate the emails from one platform to another. However, Microsoft offers a Migration Wizard (mailmig.exe) that can be applied to migrate the emails from Lotus Notes to MS Outlook, but it has a restriction that the mailbox size of more than 1 GB items cannot be processed. To counter this limitation, users can look for a third party NSF to PST Conversion tool that is capable of migrating number of emails from lotus notes (NSF) to MS exchange server (PST) files. By using this utility, one can quickly convert NSF to PST and in turn transfer emails, email attachments and other mailbox items from Notes to Outlook. With this NSF to PST conversion software, users can accurately convert emails, contacts, tasks, calendars, journal, etc., it also preserves their properties, data structure and metadata (To, For, BCC, CC, Date/ Time, Sender, Recipient, etc).
