Simple Process to Import Mac Outlook Files to Lotus Notes NSF format

June 15, 2023

Similar email programs to Windows Outlook include IBM Lotus Notes and Mac Outlook (Outlook for Mac). Lotus Notes is a well-known secure, safe, and versatile email client that is used to send and receive emails as well as to plan appointments, surf the web, and access other corporate applications. Thus, importing Mac Outlook (OLM) into IBM/Lotus Notes is occasionally required.

The Lotus Notes Software and Domino software employ the Notes Storage Facility file extension, or .nsf, to store emails, appointments, documents, and other mailbox contents. The .nsf file format is used to hold all Lotus Notes files.

In order to enable Exchange connectivity from the Mac environment, Outlook for Mac was primarily created. The mailbox items are stored in files with the .olm suffix.

Since NSF and OLM both have distinctive storage architectures, NSF files cannot be directly accessed in OLM. Therefore, we must export Outlook’s mailbox contents to Lotus Notes for Mac.
