The wizard runs fine, but there are 1600 errors. After a look to the log, it seems that NME is not able to parse the SMTP address correctly, which is generating an error for each user. Reviewed the person document of some failing users, and the Internet Address appears correctly, there is even no spaces after or before the value, and the users are using those address without problem.
Some email addresses appear with a " ' " symbol at the beginning or at the end.... It may be generating the problem. But again, there is no " ' " in the Internet Address in the Person document in Notes.
This was caused by a corruption in the Global Domain document for the Internet Domain.
Correct the Global Domain document, run the Find Internet Domains in NME and then re-run the Export Notes Directory.
This will result in a successful run of the module.
