I am trying to migrate several IBM Lotus Notes NSF files to EML format so I can move the data into a more modern email client. However, I keep running into different conversion errors during the process. Some NSF files fail to export completely, while others show issues like missing emails, broken folder structures, or partial data. I am not sure whether the problem is with the NSF files themselves, the tool I am using, or incorrect migration settings. What are the best practices or reliable methods to avoid errors during NSF to EML conversion?
