Two popular ways to export NSF files to Outlook 2016 and other versions

IBM/Lotus Notes, like MS Outlook, provides features like address book, e-mails, calendaring, and scheduling. But Lotus Notes stores the emails and other data in Notes Storage Format (NSF files) whereas MS Outlook stores all the data in PST format. And this difference in their formats can be an issue when users want to switch from one email client to the other.

Why many organizations prefer MS Outlook over Lotus Notes?

MS Outlook and IBM Notes are highly efficient applications and are used widely by individuals and corporates. But still, MS Outlook commands the major share of the market compared to Lotus Notes. There is a perception that MS Outlook is better than Lotus Notes, and the reasons for the same are:

Easy to use – Lotus Notes has a complex interface, whereas MS Outlook has a user-friendly interface. Using Lotus Notes is tough for a normal user. But configuring and using MS Outlook is easy even for non-technical users.

Cost efficient – Lotus Notes is quite costly to purchase. Its maintenance costs are also high. However, it is not the case with MS Outlook (as it comes with MS Office Suite).

Configures multiple accounts – For Lotus Notes, separate login is required for each email account which is quite time-taking. But, MS Outlook allows users to configure multiple email accounts.

How to migrate from Lotus Notes to MS Outlook manually?

MS Outlook cannot access emails in NSF files. So, while moving from Notes email client to Outlook, one has to convert NSF files to PST format. But both these email clients do not have any feature to convert NSF files to PST directly. But there is an indirect method that you can follow:

  • Open Lotus Notes (IBM Notes) and select the NSF file to be converted.
  • Go to File menu, and click Export.
    Open Lotus Notes
  • Now, in the Export wizard, enter the file name; in the Save as Type drop-down list, select Comma Separated value.
    enter the file name
  • In the CSV Export dialog box, set your preferences, and click OK.
    set your preferences

Now, the NSF data will be exported to CSV file. After that, you have to import the CSV file to MS Outlook. In MS Outlook, follow the below steps to import the CSV file

  • Start Outlook. In the File menu and click on Open & Export Import/Export.
    click on Open & Export Import/Export
  • In the Import and Export wizard, choose Import from another program or file option. Click Next.
    choose Import from another program or file option
  • In the Import a File wizard, select Comma Separated Values and click Next.
    select Comma Separated Values and click Nex
  • Browse and select the CSV file you want to import and also select the options. Then click Next to proceed.
    Browse and select the CSV file
  • Select the destination folder to which you want to import the CSV file. Click Next.
    import the CSV file
  • Finally, click Finish to start the import process.
    click Finish to start the import process
  • Now, wait till the import process gets completed.

This manual method is entirely free. However, it is time-taking, particularly with large-sized NSF files. So it is better to use a reliable third-party tool for NSF to PST conversions. Tools like Lotus Notes to Outlook facilitates quick and hassle-free Notes to Outlook migration.
