If you have a large collection of OFT files and need to access them in Lotus Notes, manual conversion is not an option. Batch conversion is the fastest way.
I tried eSoftTools OFT Converter Software to convert a folder of OFT templates into NSF, and it worked flawlessly. No data loss, no crashes, and the preview panel made it easy to verify emails before exporting.
Great tool for IT teams or admins handling corporate-level migrations.
