How to open a Google Takeout MBOX file on Windows
You downloaded a Gmail mail export from Google Takeout, but it is an .mbox file rather than separate messages. An mbox is a mailbox file: open it in a reader that lists the messages, then choose the email you want to inspect.
Read the downloaded backup on your PC
MSG, EML & PST Viewer opens .mbox and .mbx mailboxes, including Google Takeout mail exports and Thunderbird mail folders. It reads the selected email rather than loading every message's contents at once. You do not sign in to Gmail or upload the backup to use the viewer.
Open the file with the app
- Locate the mail export you downloaded. If it is inside a ZIP archive, extract it first and locate the .mbox file.
- Install MSG, EML & PST Viewer from Microsoft Store and open the .mbox or .mbx file.
- Browse the message list, or search by subject or sender, and select an email to read.
- Open or save the attachment you need individually. Keep the original mailbox when creating exported copies.
- If you need a separate export, use Pro to save mailbox emails as EML/PDF or the email list as CSV.
What is free?
- Open .mbox and .mbx mailboxes from Google Takeout or Thunderbird.
- Read messages and search their subjects or senders.
- Open and save attachments individually. Remote images are blocked by default.
Save and export with Pro
Pro is a one-time purchase with no subscription. Check the Microsoft Store purchase screen for the current price.
- Save emails as PDF or save mbox emails as .eml.
- Export a whole mbox to PDF or EML, keeping the folder structure.
- Save the email list as CSV, or save all attachments of an email at once.
Limits and things that may be missing
- This is a local viewer, not a tool for sending, editing or repairing the mailbox. Opening a downloaded backup does not import it into a Gmail account.
- CSV export is an email list, rather than a complete replacement for email bodies and attachments.
- Damaged files are read only as far as possible. The app does not reconstruct missing messages or attachments.
Choose EML/PDF when you need exported messages and CSV when you need the list. Reading and searching the backup does not require Pro.
