I'm asking this question so I can post some helpful information for people wanting to create a backup of their profile.

If you are using Windows OS and you got your download from the official website: https://www.thunderbird.net/en-US/thunderbird/all/

How do you locate the correct folder to backup? The backup must contain everything, profiles, mail accounts, emails, address books, calendar, preferences - the lot. The backup can be used to transfer between computers.

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

I use vertical view. Hate threading so that's turned off. I use a medium to large message pane. Recently been having issues with column visibility. Not sure if this is new or whether it's that I've come to a Linux client from a Windows one and there's a setting I missed when I set up the client.

Essentially dragging the column divider doesn't work properly (for me). The columns always seem to auto adjust width. Similarly if I resize the message pane the columns don't remain fixed they auto adjust.

I don't find this helpful. I prefer to set up the columns to display the amount I want/need in subject and From and I truncate the date to simply not display time.

How do I set column widths to remain where I put them? Or is this function now lost.

Hi, I had/have an IMAP account at my ISP Host, with TB connecting to.

There has been a number of occasions where I have used the Servers IMAP copy of emails as a back up, and from memory am sure that when connecting a fresh client, all emails/folders etc updated and down loaded from the server > client, in fact nothing got deleted on either side, and both sides synced.

My host (Fasthosts - I will name and shame) deleted my whole IMAP account by mistake.

They hastily re-instated just the package but all the emails had been wiped from the server.

I did though have a full copy of all emails on my TB IMAP client.

When I reconnected my client to the server after the re-instatement, i expected my clients emails to upload to the server, but instead they 'vanished' - and I have nothing but empty folders.

Am I able to recover any of these emails from my client, ie are they sitting in a file/folder still ??

TB has restarted a number of times since, and I fear the folder may have been compacted, but I cannot be sure.

Thoughts appreciated.

Thunderbird is very glitchy and slow after the latest update - Thunderbird 140.11.1esr (20260522210329)

Especially, when I get a new email, Thunderbird stops responding for 5-10 seconds and then starts working.

I am using Windows 11

Hi! I'm hoping you can help me! I use Thunderbird, and have for many years, and I love it. My computer is on its last legs, and I'm trying to save up for a new one, but, yesterday I did something possibly stupid... (yeah, I know, you NEVER get people asking for help who've done stupid things, so this will be unusual... lol). Anyway... I turned my computer on and got a popup saying that my Thunderbird needs an update and it's been a while since I updated, so I hit OK on the update... Well, my arsehole of a computer chose that exact minute to shit itself and die. When I tried restarting it, my Thunderbird no longer works. Now I have a popup with a big red X that says "The installation seems to be corrupt. Please check your hardware and disk setup and/or re-install." Can you help me? I desperately need to check my email and have one I need to send. I don't know what to do. I've also got YEARS worth of emails sitting in the system, so I can't risk losing them, either. Please help. L.

I use Thunderbird 140.11.1esr with Ubuntu 24.04. I also use LibreOffice 26.2.

When using LibreOffice, if I want to delete a number of contiguous characters, I put the cursor at the start of the characters I want to delete, press the delete key and hold it. Holding down the delete key means that delete works its way through all the characters I want to delete.

When using Thunderbird, if I want to delete a number of emails, pressing down and holding the delete key doesn't result in the deletion of a number of emails. Instead, I have to keep pressing delete again and again.

Is there some setting in Thunderbird that I can change that will result in delete automatically working its way through all the emails I want to delete?

Thanks,

Leslie

I have email [edited from public] @riverplazatravel.com purchased through Rackspace For days, on my emails through Thunderbird, I'm receiving emails but SENT emails disappear. They aren't showing in TRASH anymore, or SENT....they are disappearing and I have to check with my customer and they aren't receiving them. Big problem. Please help I've spent hours of research and dont understand much of that and so many are outdated. I've messaged and called various people. Your email was provided to me by Rackspace.

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

Can't get email from Comcast server any more & a lot of existing emails disappeared. Was on the phone with them & reset ports & checked other things but it didn't work. I can read them at Comcast's site & also send & get them there. Also can you help me forward my email to another email program?

Dear all,

For aprox. 3 weeks now Thunderbird asks me a short time after startup for a login.

It shows up a dialog with the text : "https://caldav.gmx.net verlangt einen Benutzernamen und ein Passwort."

The problem is, that I maintain several GMX - accounts and I've no idea, which credentials I have to enter :/

How can I find out ( without inspecting or debugging the source code ;-) )

THX in advance and best regards!

Hi all,

I've been using Thunderbird for eons but yesterday morning it started freezing up constantly.

It freezes up ("Thunderbird is not responding") every time new emails are received or any time I take any action while the Inbox folder is open. So, if I delete an email it freezes for a few minutes. If I do anything pretty much, it freezes up for a few minutes. Then it comes back and I can do another action, and it freezes again. This only seems to be happening when I have the Inbox open - if I go to other folders it seems to function normally.

Things I've tried without success: - Troubleshooting mode - Adding exceptions for my profile folders to Windows Defender - Compressing Inbox (and Trash and Junk) - Repairing the Inbox index

This doesn't appear to be a memory issue - right now, memory use for my entire system seems to be hovering at just over 50%. But Thunderbird is still freezing.

My Inbox folder is very large, but it's never been an issue before and nothing significant was added yesterday when it started failing.

Any suggestions appreciated!

Thanks

Yesterday I had to change my Spectrum email - I have an old road runner email address and swapped over to spectrum.net server from the old server. In this process I had to update my password to access the server.

When I updated per the instructions from Spectrum I was able to do a normal download into my Thunderbird inbox. This triggered me having to input the new password. I did check the box to update the password and save it. After the one time download I cannot get Thunderbird to download emails. I can send emails with no problems but cannot download. No way can I get a download - it does not on initialization, at the set time nor with the manual request.

Spectrum is no help - their web mail works and it's my problem. I realize this is an old system, legacy and all that - anybody got a magic fix?

Any idea on how I messed this up?

Thanks.

I'm not sure exactly when this problem started but it could have been when I had to move my primary email from Xfinity over to Yahoo. Also not sure if this started after a recent Thunderbird update. I can not send new emails nor can I forward old emails. Haven't tried reply but suspect it is the same. This is the message I get: Sending of the message failed. An error occurred while sending mail. The mail server responded: Request failed; Mailbox unavailable. Please verify that your email address is correct in your account settings and try again. All settings and passwords are correct as I can receive and send from all my different accounts using browser. I can send emails from my accounts, on my iphone, though not using Thunderbird on iphone. Account settings and passwords are the same on the phone.

I have forwarded (from my Thunderbird account) an email from our local hospital about an appointment to my mailfence address three times now, but all three were deemed undeliverable by the mailer-Daemon. I removed all links on the third attempt in case that was the problem, but no luck.

Error code: 554 Rejected : Spam ?

For further assistance, please send mail to postmaster.

How do I do that? Is my question. Is there a 'Postmaster' address to use?

Many thanks David Edwards

I had to log in this morning, the first time as its automatic, and when i did all my folders and emails have gone. Where are they as there is important information in there which i need. The page layout is different too as i can't delete anything. HELP

My apologies, but I am not good at searching documentation and Q&A history without a glossary and ontology,

That is to say every (software) ecosystem has their own culture (tacit knowledge) and language (jargon)

I want to install mail user agents and web browsers on diverse systems, from e.g. RaspBerry Pi / RiscV etc. to desktops, laptops, on-prem hardware, and multi cloud distributed virtual platforms.

It would be nice to have a subset of the same server configurations and User Interface / Ergonomics descriptions (CSS) everywhere.

Regardless of machine architecture, kernel distribution, package manager, ad nauseum.

I used to be able to do this with trusted hash verified source or binary (reel-to-reel tape) or SHA256, e.g.), and trusted certificates. (e.g. pgp)

What we used to call tarballs for source, and RC configurations per user and per (virtual) machine.

I am SICK of Jenkins / Ansible / Dpkg / apt / yum / yaml / Nix .... as well as Snap, Flatpak, etc. etc. All in incompatible versions. I used to be able to create self-extracting shell archives that Just Worked on everything from mainframes to personal computers.

I CAN compile and run and modify ancient FORTRAN, COBOL, APL, LISP, and SnoBol without these headaches. I got paid very well to do this for Y2K in 1988-1999

Please take your time answering this screed.
