How to Convert Lotus Notes (NSF) Emails to Outlook PST Format

If you are migrating from IBM/HCL Lotus Notes (NSF files) to Microsoft Outlook (PST files), you’ll need to convert your data because Outlook cannot directly open NSF files.

Manual Methods (Complex & Limited):​

  1. Using the Export Option in Lotus Notes
    • Open Lotus Notes and go to File > Export.
    • Save mailbox data in CSV or Structured Text format.
    • Open Outlook and use the Import/Export wizard to import CSV into PST.
    • Limitation: Only basic emails and contacts may transfer. Attachments, calendar, and formatting often get lost.
  2. IMAP Configuration
    • Create a new IMAP account (e.g., Gmail).
    • Configure the IMAP account in Lotus Notes and sync data.
    • Then configure the same account in Outlook and move emails to PST.
    • Limitation: Works mostly for emails, not for full mailbox migration.

Easier & Reliable Method:​

Since manual methods are time-consuming and incomplete, most users prefer a professional tool. An ATS NSF to PST converter can:
  • Convert entire mailbox including emails, contacts, calendars, attachments, and tasks.
  • Preserve folder hierarchy and metadata.
  • Support large NSF files without data loss.
  • Allow selective migration (choose specific folders to export).
  • Compatible with all versions of Lotus Notes, Outlook, and Windows.

Conclusion:
For a few emails, you can try the manual export/import method. But if you need a smooth, quick, and complete migration, using a dedicated ATS NSF to PST converter software is the best option.
