Top 2 Methods to Import MBOX File to Google Workspace

This section contains two methods, one is manual, and the other is a professional method. Using the manual method is a time-consuming and technical process; it only works for a few files. If you want a fast and secure way, you can go for the professional method by using the MBOX Converter Tool.

How to Import MBOX into G Suite Manually?

In this method, we are using Mozilla Thunderbird as a bridge to move emails from an MBOX file into Google Workspace. This method imports offline MBOX data into Thunderbird and pushes it to Google Workspace through IMAP synchronization.

Steps to Migrate MBOX Files to Google Workspace

  1. Firstly, download and install Mozilla Thunderbird on your computer.
  2. Then, open Thunderbird, and go to Tools > Settings.
  3. After that, navigate to Account Settings > Account Actions.
  4. Afterwards, click on Add Account and continue with the setup.
  5. Now, configure your Google Workspace account using the IMAP settings.
  6. Next, install the ImportExportTools NG add-on in Thunderbird.
  7. Then, use the add-on to import the MBOX file into Thunderbird’s Local Folders.
  8. Thereafter, drag and drop the imported MBOX emails from Local Folders to your Google Workspace account in Thunderbird.
  9. Once done, the emails from the MBOX file will sync automatically with your Google Workspace.
  10. Finally, log in to your Google Workspace Gmail to access all the imported emails.

Shortcomings of the Manual method:

  • You must keep Thunderbird open and connected until all emails sync, which can slow down your computer.
  • Not for organizations with multiple users and large data volumes.
  • Sometimes attachments don’t transfer properly or get corrupted.
  • For large MBOX files or multiple accounts, dragging and dropping messages takes a lot of time.
