IBM developed Lotus Notes, an adroit email client application in year 1989. It acts as an integrated email client application that collaborates with IBM Domino Server. The staunch email application allows user to access business emails, applications, attachments, contacts, appointments, events, tasks, journals, and calendars. The Lotus Notes application is widely compatible and can work flawlessly on multiple operating systems like Windows, Linux, UNIX and Mac. Lotus Notes and Domino Server both store files in the form of NSF format. Lotus Notes consists of a distinguished feature of application development hence it is also compared to Microsoft SharePoint. The user friendly interface of Notes allows this application the functionality to access, store and present data in safe and secure environment. However there are multiple ways by which Notes NSF files get malfunctioned. In this article I would like to draw a light upon one of the common situations when Lotus Notes user finds difficulty while accessing NSF data.
