I have several MBOX files with me and I want to import MBOX files into the Thunderbird email client. I've come across different methods, including manual techniques and third-party tools, but I'm unsure which approach is the most efficient, especially when dealing with multiple or large-sized MBOX files. Some methods also seem complicated for users who are not very technical.

Suggest me any reliable tool for this!

Yes, I'm running unsupported Win 7

And yes, I could not find anything in the "help" system that related.

I maintain a Hotmail account and copy traffic to my local system. Upon reboot Thunderbird shows some files from 2024 and no local folders where I stored all my re-directed traffic.

I've run some system / disk checks and no obvious problems.

Any thoughts besides upgrading to current OS etc? Is there a Thunderbird backup solution to move files away from the active drive to protect them?

I bought Thunderbird because Gmail kept telling me I reached my 15gb limit. I thought I could transfer my emails to my local hard drive thereby freeing up my Gmail account. Now Thunderbird is saying I have reached my limit as well. Is there a limit on transferring emails to your hard drive? What am I doing wrong?

I just had a support session and the tech was unable to solve the problem. We tried installing a new version of Thunderbird and importing the messages over from the default install and it just freezes up. He tried replacing account settings with the account settings from a previous version and that didn't work either. He suggested contacting Mozilla to see if there was a way to import messages from the frozen default to my new profile.

Move Thunderbird 32 profile to new computer with Thunderbird 64

I am moving my Thunderbird (32 bit) data from an old Win 7 computer to Linux Mint on a new machine with Thunderbird 64 bit. I have followed all the advice to copy the old computer profile to the profile folder in Mint, but nothing appears in Thunderbird. My pop3 email server has 2-factor authentication; I can set this up and access or send new emails, but I can't import all my old email folders. The old Thunderbird is version 115.18.0 (32 bit) and says it is "up to date on esr update channel" The Mint Thunderbird is 140.0.6 esr (64 bit) and was recently installed with Mint.

As these versions are 32 bit and 64 bit respectively, I don't see how I can make them the same version, as recommended for transferring profiles.

How can I make this work?

Hi, I accidentally deleted all my emails on my desktop. I was in Account Settings and pressed the red "Delete" button that appears next to the account name on the screen. I was trying to reset the email account settings but when i pressed delete, the mail account and all my old messages were deleted from my desktop.

I do see a file in the folder in User/appdata/roaming/thunderbird/profiles.../mail/mail.server.co.za that says "Inbox" and I THINK that might be my old emails but I can't seem to get Thunderbird to open the file. I've tried using ImportExportNG but it still won't open that file.

Is there a way to recover my old emails without having to take my computer to a specialist?

Appreciate any help. Hani

A couple of months ago Thunderbird installed a new version (150.0.2) that made me enter a new identity. After I did that, I tried importing the e-mail folders from the earlier version (139.0), but totally without success. So I tried re-installing an older version, but this also, was no longer able to import the folders stored on my hard drive. What can I do????

The newest version of Thunderbird wiped out the stored files from the previous version by making me create a new identity. I have tried several times to use "import" to retrieve backed up data from the old version, but without success, even after I re-installed an earlier version of Thunderbird. Each time I use the "import" feature I get a message that it failed unexpectedly. I need these old e-mails because they contain receipts for charitable donations that I need because my tax returns are being audited. What can I do?

Hi, I am Div, and I have a large number of EML files which I want to send to Thunderbird. Can anyone tell me the best ways?? I know the manual method, but it didn't work out for me because I want my files to be imported safely in bulk, as it is my daily work. I want a reliable solution. Will be really thankful if someone suggests a safe and quick solution.
