Hi panel,
I’m trying to import an MBOX file into Thunderbird, but the import option is greyed out in ImportExportTools NG. I double-checked the add-on installation, restarted Thunderbird, and even tried an older version—still no luck! Is there some hidden setting I’m missing?
Rather than wasting time troubleshooting, I used SysTools Thunderbird Import Wizard, and it worked like a charm. If anyone is struggling, try this tool to import MBOX to Thunderbird. Has anyone figured out a manual fix?
