Email migration has grown to be quite common nowadays. Organizations are switching from costly and complex Lotus Notes to an overall better email client such as Outlook. Thus, giving rise to a query: How to read NSF file in Outlook. The article focuses on the entirety of such an issue and provides relevant answers.

Introduction: Lotus Notes is a highly secure email client used in multiple organizations. Recently, a new and improved Lotus Notes 10 has been released which incorporates further features to enhance data security. However, it lacks some basic user necessities when compared to other cost-effective applications such as MS Outlook. Working on Lotus Notes is too complicated and a new user cannot get started on it right away. It saves its data in NSF format.
MS Outlook, on the other hand, is the spearhead of email clients – the most popular among individuals and organizations alike. It is largely due to its easy-to-use interface and powerful data management capabilities but affordability. Outlook saves its data in PST format.

Some common reasons that require users to read NSF file in Outlook are:
MS Outlook has a user-friendly interface that is unique to the user’s needs.
Outlook offers better data management capabilities on an overall basis.

Important Note: After the careful implementation of this procedure in our lab, we found many issues that defame the entire manual method on the web. Here we will explain them individually:
#Issue 1: The exported file has no extension which hinders the import option in MS Outlook
When trying to import the exported Lotus Notes file in MS Outlook, the application cannot locate the Notes file. This is because the exported file has no extension attached to it.
#Issue 2: Problems in Mapping of CSV files after renaming the extension
The common notion to overcome the previous error is by renaming the extension of exported notes file into .csv.
But even after doing that, there will be problems while mapping the values during Outlook Import function. Several texts in the message body appearing as “***” signifies the compromise in the formatting of emails.
#Issue 3: Loss of Data Integrity and Email Attributes
Even the mapping of items is done and the file’s data is imported successfully, the result will be several emails missing headers, formatting issues, and broken images.
The reason all these issues are appearing is that CSV files are used for contacts and reports, and not for storing hundreds of emails. Other than this, the process is a monotonous one, as only one account data can be moved at a time.
To overcome such issues, the use of a third-party software application is required. It will allow users to read NSF files in Outlook in bulk without the formatting and missing attributes issue.
