If you want to convert NSF to MBOX, I recommend you use the Professional solution NSF to PST Converter tool. It allows the users to perform bulk migration of NSF to PST without any alteration in the original data. It keeps the crucial data intact during
the whole conversion process. You can also go for the manual approach, but as we know, the manual method does not always provide reliable results and is also a time-consuming process.
