While migrating certain Notes messages with Migrator for Notes to Exchange (MNE) an IBM Notes Error Notification (nsd.exe) may pop up reporting the Notes client has crashed. The migration aborts, and the log contains references that the process launched to migrate the user has failed. A warning message "WARNING: [4059-33-298-00009E03] Unable to export RTF body for msg:" is written at the end of corresponding user log.
Use the [Notes] SkipNotes INI parameter to bypass those messages. Please see MNE Program Parameters Reference for more information.
