If you are planning to switch from Lotus Notes to Outlook client, you have come to the right place. In this article, we will be discussing how to export email messages and other data from NSF to PST clients. Keep reading this article to convert NSF to PST.

Lotus Notes and Microsoft Outlook are two popular email clients used by millions of email users worldwide. Although both are mainly used as an email application, they are different from each other. I have often seen that many users switch from one email client to another. There are plenty of reasons why users may need to change their email client. But switching from one email program to another can be a daunting task for users. Let us suppose that you were using the Lotus Notes client in your previous organization. Now you have switched to a new organization where you need to use Microsoft Outlook, a different email client. What will you do? Both these email clients create different files to store the mailbox data. So you cannot import or export your old email messages from NSF to PST just like that.

Lotus Notes

IBM Notes, formerly known as Lotus Notes, is just an email client for many people. Although email is probably the most distinct part of Lotus Notes, it has many other features as well which includes instant messaging, calendars, blogs, personal directory, and online forums. Just like any other email client, it also uses the standard-based mail protocols such as POP3 and SMTP.

IBM Notes creates a database file to store all the collaborative business information such as email and calendar data. This database file is saved in NSF aka Notes Storage Facility format that stores data in document units called “notes”.

Microsoft Outlook

On the other hand, Microsoft Outlook is one of the most popular email clients around the world. It is a part of the well-known Microsoft Office suite. Although it is mainly used as an email application, it provides you many useful features like contact manager, calendar, task manager, note-taking, journal, etc. It supports POP3 and IMAP protocols that enable users to import emails from servers that support these protocols.

Microsoft Outlook stores all the mailbox data into an Outlook data file called PST (personal storage table). The mailbox data includes email messages, contacts, calendars, notes, tasks, journals, etc.
