I used the IBM Notes, e-mail client, to manage my e-mail, contacts, and calendars. Unfortunately, this year we received a notification from IBM that it will no longer support the Notes client and Domino server. The Notes e-mail client will be operated by HCL Corporation.

The real problem begins at this point. I haven’t received updates since their end. Although I was looking for HCL Notes test settings, I didn’t get it. Right now, I have decided to switch from Lotus Notes to the Outlook email client.

When I checked the source data format for the Lotus Notes client, it was saved in the * .nsf file format. But I can only import PST files into Outlook. So, I started converting NSF files to PST format. There are two ways to convert NSF documents to PST documents.

  • Professional tool for exporting NSF files to PST

The big question is, which solution should I prefer?

You will encounter a problem during the recovery process. The cPanel e-mail backup file is encoded into a single file. This means that if you try to manually restore cPanel backup emails, you may not receive exactly the same information.

Manual Way to Free Convert NSF File to PST:

A user can free convert NSF Files to PST file format without changing any original information of IBM Notes mailboxes. He can do it just by following the given steps:

1). Export NSF Files to CSV

  1. In Lotus Notes Mail Client, click on the File menu & choose the Export option.
  2. Give a name to save the file & select the CSV option from the saving format list.
  3. Setup all the options according to your needs in the CSV Export window.
  4. You will get CSV files at your desired output file saving location.

2.) Import CSV to Outlook Email Client

  1. From the File menu of Outlook, choose the Open & Export option.
  2. Select the Import/Export option.
  3. Choose Import from another program or file option.
  4. Select the Comma Separated Values option & click on the Next button.
  5. Select the CSV file you obtained from the Lotus Notes mail client.
  6. Your CSV mailbox items will get imported into the Outlook mail client.

Why Converting NSF to PST Manually for free is a Bad Idea?

The biggest problem with manually exporting NSF files to PST is that all your data may not be converted correctly. It is a very difficult task, so non-technology boys are advised to do so at their own risk.

During the manual process, the user will only migrate NSF emails and contact entries to the PST. No CALENDAR items will be migrated to the Outlook mail client.

The whole process is very tedious, boring, and time-consuming. Outlook cannot be used during the entire import process. The user must have both the IBM Notes e-mail client and Outlook installed on their computer.
