I need to export Gmail to PST but without losing my email structure. After searching, I found the MailConverterTools Gmail Email Backup Tool, which works perfectly. It exports Gmail emails into PST and many other formats like EML, PDF, and MSG. The tool also allows you to migrate Gmail data directly to Office 365, Yahoo, or Thunderbird. A great feature is that it maintains folder hierarchy and data integrity throughout the backup, so nothing gets misplaced. Apart from this, the tool lets you back up only the emails you need using the Date Filter. Just set a start and end date to migrate important mails selectively.
