When doing a migration the following error occurs:
ERROR: [4618-33-118-00000000] Unable to open NSF file
This caused if the file location in the TSV file is incorrect. You will see the following in the log file also: " Path is a directory"
1- Check the TSV file to make sure that the Mailfile path has been correctly specified.
2- Make the correction and re-run the migration.
Make sure when editing the TSV that the entry for the MailFile path is all in the same column in Excel
