When running Notes Migrator for Exchange you may recieve the following error:
"Error: Invalid NSF version."
You will recieve this error if the installed Lotus Notes client version is not compatible with the version of Lotus Notes that created the nsf file originally.
When running Notes Migrator for Exchange, the Notes Client version on the migration machine must agree with the version of Notes under which the NSF file was created.
To resolve this issue please update the Lotus Notes client on the migrator desktop machine.
