Import Gmail mbox archive in Thunderbird

Posted

HI, I read former posts re problems importing Gmail *.mbox archives into Thunderbird (9GB; not compressed, is readable by commandline "more") .

The following steps have been done:

After copying mbox file to Thunderbird "local folder" place, no messages show up.

Same problem has been described before but my archive is NOT compressed. How to proceed? Thanks a lot for your help christian

I'd still be careful with mail files greater than 4 GB.

In any case, when your problem has been fixed, can you mark the thread as 'Solved' please? Thank you.

make your archive less than 4Gb is the first step.

Hi Matt, I split the file in 3 parts, all considerably smaller than 4GB (around 3 GB), put one in the thunderbird local folder place. To no avail. Same result as before. What else can I do?

Please provide the full path where you copy the mbox file to, including the name of the file.

Note, you'll need to do this while Thunderbird is closed.

This is the path:

C:\Users\braun\AppData\Roaming\Thunderbird\Profiles\813pg5a5.default\Mail\Local Folders

and these are the 2 files in there (from 2 because altogether almost 10GB): Alle E-Mails einschließlich Spam-Nachrichten und E-2_1.mbox (3.1 GB) Alle E-Mails einschließlich Spam-Nachrichten und E-2_2.mbox (3.1Gb)

Both are ASCII files, no compression Thanks for your help Christian

Sorry, from 3 files altogether because I was told, the mbox-file should not exceed 4GB.

Alle E-Mails einschließlich Spam-Nachrichten und E-2_1.mbox

What a crap file name is this? Mbox files don't have a file extension. Try something simple, e.g. like 'E-2_1' (without the quotation marks).

Upon restarting Thunderbird, there should then be a folder E-2_1 underneath Local Folders.

Hi Chris, this name has been made by the Gmail Archiving Process, but it is not a name problem because the folder with this name appears in "local Folders". It is just only empty!

Tried it again with short name. It worked! Great thanks. A lot!

Can one also restore the folder structure from before in Gmail? Now everything is in one big bucket :-)

I suppose you'd need to manually re-create the folder structure and move messages manually to their designated folders. But then I never downloaded my message archive from Google, and I have no idea how they organize the download. May be what you get is just the 'All Mail' folder. If in doubt, ask Google.

After this, I tried the original 9GB file again with a short name: It works too.

There is no limitation on 4GB on mbox files as Matt has mentioned.

Thanks again, you helped me access all my professional emails again!
