Exchange Server is a mail server which enables you to send or receive e-mails and stores entire data into an EDB file, but the EDB file can be accessed only in the exchange environment. If you want to access an EDB file outside the exchange environment, then you need to convert it into another file format. So you can use EDB to NSF Converter tool which can easily convert entire EDB file data without loosing any single piece data, I also used an EDB to NSF Converter which works well you can also use it for this link:- http://www.nsfsecurityremover.com/edb-to-nsf.html
