Many users export their MBOX files from Google Takeout or other MBOX-supported email clients like Thunderbird, Apple Mail, and many more. Uploading MBOX files to Google Workspace is a common requirement for individuals and organizations who want to manage all their mailbox data in one place. Moving email data in the MBOX format to Google Workspace makes the email migration aspect all the more crucial for the fact that data is now being exported into an even secure and accessible environment.

This migration is not directly possible as Google Workspace does not officially support MBOX files. This creates an incompatibility issue, risk of data loss, attachment may not be preserved and folder structure may not be maintained.
