“Is there any tool that supports both selective and bulk TGZ to MSG export?”

[Midnight Rider]

Yes, the BetaVare Export TGZ to MSG Tool provides support for selective as well as bulk modes of TGZ to MSG conversion. It allows users to export a single folder or a few selected folders or an entire TGZ mailbox in one go. The tool works accurately for any larger-sized files without compromising the structure of folders and metadata. It also provides an option for previewing emails that helps verify the content before exporting them. The tool is suitable for both beginners and professionals during conversion. Its offline working process keeps privacy and gives full control over data. A free demo is available for testing.
