Google Takeout not working for Gmail? Common problems and fixes

Quick reference: Takeout’s limits

A handful of numbers explain most Takeout trouble. These come from Google’s own help pages at the time of writing:

Keep these in mind and plan around them: start the export when you’ll be near a good connection for the following week.

Symptom: the export takes days, or the email never arrives

Likely causes: a large mailbox (Google’s help says preparation can take from a few minutes to a few days), other Google products still selected, a mail filter hiding Google’s email, or a request made while signed in to a different Google account.

Fixes:

• Open takeout.google.com and check your exports there. Takeout lists exports in progress and ready ones with a download button, so you don’t depend on the email.
• Check you’re looking at the right account. If you have several Google accounts, the email goes to the address of the account that requested the export.
• Search the mailbox (including Spam) for mail from Google about your data, in case a filter archived it.
• If the export was huge, consider starting again with Deselect all and only Mail ticked. Photos and Drive are the usual reasons a “Mail export” takes forever.
• If it’s been several days with no progress, or Google reports the export failed, create a new one. Google’s own advice for a failed archive is simply to try creating another.

Symptom: the link expired, or you’ve hit the download limit

Likely cause: archives stay available for about 7 days, and each archive can be downloaded only 5 times. Interrupted downloads that you restart from scratch count towards the five.

Fix: there’s no way to extend or reset an archive; request a new export. To make the next one stick:

• Download as soon as Google’s email arrives, and download every part, not just the first.
• Use a stable wired or strong Wi-Fi connection and stop the computer from sleeping during long downloads.
• Download parts one at a time instead of all at once, so a flaky connection only costs you one attempt on one part.
• Use the browser’s own download manager to resume a paused download where possible, rather than clicking the link again.

Symptom: you got several zip files, and the mail seems incomplete

Likely cause: your export was larger than the archive size you picked on the second page of Takeout, so Google split it into several numbered files such as takeout-…-001.zip and takeout-…-002.zip. Each part is a normal archive you extract on its own, not one zip cut into slices. Your mail can sit in any of them, and a very large mailbox can be spread across more than one part, with more than one .mbox file.

Fixes:

• Download and extract every part. Don’t assume part 1 has everything.
• Look in Takeout/Mail inside each extracted folder and collect every .mbox file you find.
• Next time, choose the largest size (50 GB) to keep the number of parts down. Google notes this lowers the chance of a split but doesn’t guarantee a single file.

When you convert, upload all the .mbox files together in one conversion. MoveMyInbox accepts several files at once (zips must be extracted first) and handles up to 50 GB per conversion.

Symptom: labels, Spam or Trash are missing, or the file name is odd

A full export usually produces one file called All mail Including Spam and Trash.mbox. That’s the whole mailbox, not a special Spam folder; the name just tells you nothing was left out. Gmail doesn’t have folders, so there’s no separate file per label. Instead, each message carries an X-Gmail-Labels header listing its labels, which Google’s help confirms.

If labels seem to be missing: they’re almost always inside that header rather than lost. Mail apps that ignore the header show one big list. Converters that read it, such as MoveMyInbox with the Gmail labels folder mode, rebuild them as folders.

If whole groups of mail are missing: check whether you clicked All Mail data included and picked only some labels. A partial export only contains what you ticked, and its file names reflect that selection. Re-run the export with Include all messages in Mail ticked.

If you don’t want Spam and Trash: a full export includes them. Empty both in Gmail before you request the export, or delete those folders after converting. Remember that Gmail deletes Trash and Spam on its own after 30 days, so anything older isn’t there to export.

Symptom: Takeout says it’s unavailable on a work or school account

Likely cause: on Google Workspace accounts, administrators decide whether users may use Takeout, and for which products. If Mail is missing, greyed out, or Takeout shows that it isn’t available, it has been turned off for you.

Fixes:

• Ask your administrator to allow Takeout for your account. The setting lives in the Admin console under the Google Takeout service.
• If the whole organisation is moving, the admin may prefer an organisation-wide export or a direct migration. Our Google Workspace to Microsoft 365 post compares the options.
• Leaving a job? Ask early. Once the account is suspended or deleted, you can’t export anything, and mail from a company account may belong to the company.

Symptom: the download is much bigger than your Gmail storage

Likely cause: this one is normal. Inside an MBOX file, attachments are stored as text using an encoding called Base64, which makes them roughly a third larger than the original files. A mailbox full of PDFs and photos can easily come out noticeably bigger than the figure Gmail shows for storage.

Fix: nothing is wrong, just plan for the space. Allow at least twice the mailbox size free on your disk if you download a zip and extract it on the same drive, because both copies exist until you delete the zip. Once the .mbox files are extracted and checked, you can delete the zips. If you convert with MoveMyInbox, the price is based on the size of the files you upload, so expect that figure rather than the Gmail storage number.

Symptom: the zip won’t open on a Mac, or extraction fails

Likely cause: very large zips (and the large files inside them) use an extended zip format that some tools, including macOS’s built-in Archive Utility in some cases, struggle with. You may see an error, an endless “expanding” loop, or a result that’s smaller than it should be. A download that silently stopped early produces the same symptoms.

Fixes:

• First compare the downloaded file’s size with the size listed on Takeout. If it’s smaller, the download is incomplete and no tool will fix it; download again.
• Try a different extractor. Free tools such as The Unarchiver or Keka on macOS, or 7-Zip on Windows, often succeed where the built-in tool fails. On a Mac, Terminal’s ditto -x -k file.zip destination is another option.
• Next time, pick .tgz instead of .zip as the file type. Google notes that .tgz may need extra software on Windows, but macOS opens it with a double-click.
