Forum Bashkësie Thunderbird

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!

I am using Thunderbird 152.0 in Win 11.

I am trying to move about 100 emails from one folder to another in the same account. 1. I have selected all those emails to move and dragged them to the new location. One email moves. 2. I have selected all those emails to move, right clicked and selected Move to/email account/different folder. One email moves.

These methods used to work and all emails selected would move. For some reason they don't move except one.

What am I doing wrong now?

It was working fine on the new computer until yesterday. Now I get a pop-up box that says: ' Unable to connect The connection was refused when attempting to contact localhost.

The site could be temporarily unavailable or too busy. Try again in a few moments.

If you are unable to load any pages, check your computer's network connection. If your computer or network is protected by a firewall or proxy, make sure Thunderbird is permitted to access the web.

Hi all,

I installed Thunderbird a few months ago to transfer emails from an email account that is about to be shut down to my Google email account.

I now want to uninstall Thunderbird (and delete all its files from my computer, including emails) but am worried my Google emails will also get deleted (e.g., due to syncing?) in this process.

I would have loved to keep Thunderbird installed but, due to my personal laptop being unavailable when this email transfer began a few months ago, I had to install Thunderbird on my work laptop instead, and I do not want Thunderbird to stay on my work laptop anymore (my employer allows employees to install any software but I will feel better if I just delete Thunderbird from the work laptop at this point).

Please advise, thanks.

Using 153.0b3 and having an issue.

Under Account Settings, I have three entries in the left: Company Yahoo Local Folders

Under Company, my POP3 download/remove from server account I've had since the 90s, under Copies & Folders I have "Place a copy in" for "Sent" Folder on: Company. Same for Message Archives, Drafts, and Templates. Under Yahoo I have "Place a copy in" for "Local Folders" for all four. The ONLY reason I have them set up this way is due to the error message that displays if I try and set any of them to be Yahoo.

I recently went to find an email I'd sent last week using my Company account and couldn't find it. I couldn't find any that had been sent for awhile. I eventually found it under Local Folders(I had "Hide local folders" turned on because I can't understand the reason to it to even exist).

What exactly is going on? Is it a bug with the beta? I'm getting really tired of having to move the messages to the correct folder when all of the settings appear correct(my oldest email is from 1996 btw, so I've been keeping current since Netscape Mail)

I added thunderbird to my new computer while the old computer still had thunderbird up. I noticed that it tried to add my two account data after I created them, but the old accounts were for pop mail. After finding out that I needed to turn off getting mail (which was not working, but trying) I added the two accounts again as IMAP accounts. I discovered that I had to move my old folders to the new accounts (copy only seemed to work sometimes), but it was tricky and SLOW for large folders. The main thing I learned was that I had to click on the old folder in the pop account and move it to the TOP level of the new IMAP account. HOWEVER this was slow for many folders and did not work for the "built in" folders. I looks like files are first moved to the server, then back to the new account on the new machine. I think with all of my fumbling around trying to get the transfer to work, some of the files (it looked like they had html in them) got corrupted and would not transfer or even delete until I moved them to a temp folder in the same account, after which I could move the files which I highlighted, but I had to create the folder first. To keep things from being confusing I deleted the now empty folders in the pop account as I moved each one. As I said moving the files was slow, and until I realized this I might have tried to do moves too quickly. At any rate, when I was done I had several duplicate folders in the IMAP account when I was done. The empty ones I created all deleted ok, but there are still two copies of Draft folders in each of my accounts, one empty, one with my files. How do I remove the duplicate empty folder?

Neither my wife nor I can access email on our respective PCs. This has been the case for four weeks. We can access email by our Android phones, but we really want to use our PCs. I've tried to resolve the problem and failed. Previous to this failure, I had an account with BT but this was transferred to EE. When I attempt to log in to my mail account, I receive the message "Could not connect ... :the connection was refused". I can also add is that in my Account settings, Outgoing Mail server I see a message "Connection to server mail.btinternet.com:465 failed."

First, I have very limited understanding of software. I need very simple explanations.

Here's my issue. I use Thunderbird on my desktop computer. I have used the Import/Export > Options > Backup Scheduling function to backup my Thunderbird email to my USB/flash drive. I have labelled the backup folder on my flash drive "Thunderbird email backup." That folder contains numerous subfolders including: 1) calendar-data 2) chrome_debugger_profile 3) crashes 4) datareporting 5) extensions 6) ExternalMailFolders 7) Mail 8) minidumps 9) saved-telemetry-pings 10) scheduled-notifications 11) settings 12) shader-cache 13) storage.

Again, these are the subfolders created/named by the Thunderbird Import/Export backup. I HAVE NO IDEA WHAT THESE FOLDERS MEAN.

Here's what I want - it's actually very simple. I want to be able to see (read) my backed up email on my flash drive without using the Thunderbird installed on my computer. I want complete interaction with the backed up email without my desktop Thunderbird - or my online email account - being involved at all.

My understanding is that Thunderbird Portable is supposed to be able to allow me to do that. I downloaded Thunderbird Portable (from https://portableapps.com) to my flash drive but when I tried to access it the first thing it did was try to force me to put in my online account (POP?) information.

I don't want to do that. I just want to open Thunderbird Portable on the flash drive and have it realize that all of my backed up Thunderbird email information is right there in the same flash drive. I want it to just access and use what's right there.

I was really hoping that Thunderbird Portable would simply ask me where to look - in a very user-friendly way! - and I could tell it to go to my "Thunderbird email backup" folder on my flash drive (WHERE ALL MY THUNDERBIRD INFO IS!) and it would simply do just that and provide me with complete Thunderbird service for the backed up email.

Am I missing something? Can someone give me a VERY SIMPLE walk through to do what I would think should be a very simple thing? Thank you. Chris (6/29/26)

PS - I've read the Mozilla Support ARTICLE: Thunderbird Portable (Mozilla Thunderbird, Portable Edition) and other portable apps as alternatives (https://support.mozilla.org/en-US/questions/1285834) and it alludes in general terms to exactly what I want to do but it does not give any step-wise instructions.

Updating on June 20, the existing Thunderbird version in a flash of a second was replaced by a new blank one. All files and settings were lost. I needed an expert who (at cost of course!) managed to roll back the program with all files and settings as they were. This was a disaster, how can such effect happen? Right now I do not trust the updates anymore and will not implement new updates.

Is there any way to print a complete email conversation? I don't seem to be able to find any solution to this. I have tried various ways of displaying the conversation but none of them will allow me to print the entire conversation. Anyone any ideas?

送信トレイが消えました。 今まで送受信できていたメールアドレスがいつの日かメールの受信ができなくなってしまったため、ログアウトを行い、再ログインしたのですが、送信トレイの作成がされなくなりました。 メールを送ると添付画像のようなエラーが出てしまい、送信したメールを残すことができない状態になっているので改善策を教えてほしいです。

Hi,

I wanted Thunderbird to stop downloading messages from an old gmail account, but wanted to keep a kind of archive, so what I did was dragged all the account folders (Inbox, Sent, Trash) to Local Folders so that I can continue to reference downloaded emails (the account was using POP, not IMAP).

I'm on Windows 11. Inbox file is basically the same size as it used to be (just now in Local Folders) but Sent, Trash, other subfolders have all almost exactly doubled in filesize compared to what they were before I dragged (moved) the folders to Local Folders. I don't think there are doubles of messages when I look in Local Folders or anything.

Any ideas why the double filesizes? All the .msf filesizes are like, 15% smaller for some reason.

Thanks.

I have four different email accounts. A week ago, all incoming and outgoing traffic suddenly stopped . Webmail works normally. I have no viruses, trojans, etc. I deleted one of the accounts and tried reinstalling it. I can't do it anymore. The system keeps responding: "Unable to authenticate to the server. Username or password configuration may be incorrect." But they are all abolutely correct. I don't know what else to do. Any clue? Thanks

Migrating from a Win 10 laptop to a Win 11 laptop. Need to move the local folders as well but they were assigned a different ID and I can't change the target address in the new installation. Thanks in advance for your help. Rick.

Every time I shut down my Windows 11 PC (25H2, x86-64), it gets stuck and states "This app is preventing shutdown", listing Thunderbird as the application that is the cause for the hold. If I don't react to this and force close Thunderbird at this point, my PC does not shut down. (Annoying if I hit "shut down" and walk away expecting the shutdown to complete.)

If I close Thunderbird before shutting down, Windows proceeds correctly.

How can I diagnose why Thunderbird seems to hold Windows active?

I had an account for my business. The account was hosted on Google; but was listed among my Tbird accounts. I closed the business; closed the Email account on gmail; and, I deleted all the folders, and the like from my Tbird client, every reference to the deleted account.

I continually get requests to login to my account. See the attached image.

Does anyone have any idea as to what I missed?

Thanks!
