For Windows users seeking the best option to migrate Thunderbird to Google Workspace, I am going to recommend the CloudMigration Thunderbird Backup Tool (https://www.cloudemailmigration.com/thunderbird-backup.php#). It's very simple to work with and eliminates the need to complete any manual setup like MBOX files or IMAP settings. The tool automatically locates your Thunderbird profile, has direct migration to Gmail (which works seamlessly with Google Workspace), gives you the ability to apply filters, like date range or excluding attachments, prevents duplicate emails, and has bulk migration options, which is what saved me so much time. This has been, without a doubt, one of the smoothest tools I have ever worked with when transferring mail.

It's not easy to move Thunderbird emails to Google Workspace (previously G Suite) on Windows since Thunderbird saves emails in MBOX format, and Google Workspace doesn't have a way to directly import MBOX files. A lot of people try to accomplish it by hand with email programs and IMAP, but those can be slow, make mistakes, and lose attachments or folder structures. I encountered the same issue when I had to move my Thunderbird emails to my Google Workspace account.I tried some manual fixes that didn't work very well, but WholeClear MBOX to G Suite Converter (https://www.wholeclear.com/mbox/g-suite/) worked perfectly. The software linked directly to the Google Workspace mailbox and brought in all of the data from Thunderbird's MBOX files without losing any of it. It kept all the folders, attachments, and email attributes just the way they were.
