If you are looking to open EMLX files in Thunderbird, you have three main options:
- Manual Conversion: Rename EMLX files to EML format, then import them into Thunderbird by dragging them into a new folder.
- ImportExportTools NG Extension: Install the ImportExportTools NG add-on in Thunderbird to import EMLX or EML files directly from a folder, preserving metadata and folder structure.
- Aryson EMLX Converter: For bulk migrations, use the Aryson EMLX Converter Tool. It allows for batch importing of EMLX files into Thunderbird without data loss and preserves folder hierarchy.
