I am currently trying to migrate some old email data, and I have run into a bit of a challenge. I have several email files saved in MBOX format, and I now need to access them in IBM Notes, which uses the NSF file format. I am not sure what the safest and most reliable method is to convert MBOX files into NSF without losing email data, folder structure, or attachments. I prefer a solution that is accurate and not overly complicated, since this is important data. Has anyone here done this before? Are there any trusted tools you would recommend?
