Outlook to Lotus Notes Migration

How Do You Perform Outlook to Lotus Notes Migration?

Microsoft Outlook is an email program used for sending and receiving emails. As the lotus points out, it is also used to send and receive emails for the user. Now, why is it required for Outlook to Lotus Notes transfer if both are email clients and are utilized for email management? As a result, this post includes an answer to such inquiries.


So here’s the answer: we require this email conversion since MS Outlook and IBM Lotus Notes use distinct file types for processing and storing emails and attachments, and you can’t access Outlook-authored emails directly in the Lotus Notes application server.

The user-created email files are saved by the Outlook client using PST, or Personal Storage Table, and by Lotus Notes, using NSF, or Notes Storage Facility Both file formats are very dissimilar from one another. However, you cannot immediately convert Outlook files into Lotus Notes format. And if you do try, you can lose your email files or run into file corruption. Without professional assistance, converting from Outlook to Lotus Notes is not secure.

So, to do so, you must follow specific processes and methods that are safe and secure for converting PST emails into Lotus Notes file format without the chance of data loss. Let’s have a look at them.

Manual Outlook to Lotus Notes Conversion Methods

To convert a PST file to an NSF file, use the methods listed below.

Using the freeware utility nUpgarde exe

You can import Outlook emails into Lotus Notes manually using this method. This nUpgarde tool is part of the Notes Migration Tools and is installed by default in the IBM Lotus Notes program’s local directory. Simply install this software alongside the Lotus Notes installation process. Remember that if you want to utilize the nUpgarde program, you must install it alongside Lotus Notes.

Before running the Notes upgrade wizard, double-check the following items.

  • Instead of “Internet Mail Only,” set your Microsoft Outlook workstation to Corporate or Workgroup.
  • Set MS Outlook as the workstation’s default mail application.
  • Outlook PST or PAB files must be connected to a workstation profile.
