NSF file to pst file conversion

I am using “NSF2PST” tool for migrating NSF file PST file but it is showing the error: 1 execution code = -1

2 errno = 0

Please suggest what to do?

While in another tool “CMT Universal”, it is creating a text file with the message " Exchange DN is blank for : Manoj administrator"

CMT sounds like you are migrating directly into Exchange but there isn’t a exchange user for the mail to move to… check the CMT person doc to see if the Domino account matched the Exchange LDAP information.
