Outlook creates and stores the mailbox information and items, such as emails, contacts, attachments, etc., in a PST (Personal Storage Table or Personal Folder) file. While the IBM Lotus Notes creates and stores the mailbox items in NSF or Notes Storage Facility file. 

Thus, exporting information from Lotus Notes email clients, such as address books or contacts, to Outlook becomes a complicated process. 

In this article, you will learn steps to convert and transfer the address book or contacts from Lotus Notes to Microsoft Outlook email client using manual method and with the help of a third-party NSF to PST converter for software.
