To be clear, I seriously doubt the problems I am encountering are TB's fault! The problems may be my fault since I've grown older, I've tended (believed) using new versions of software present my mind a BIGGER challenge than using the older software/version I have been successfully using? I'm still using Version115.10.1

After our ISP chose to start using Zimbra Oct. 7, 2025 and their tech support could not assist me in getting TB working the had me remove POP3 settings for TB and change to IMAP with their software.

FINALLY someone helped me get TB working with IMAP. For 3 days grrr. Now the ISP says I need to use their web mail, Zimbra.

So might downloading the current TB version and somehow get the In box, all the folder contnets etc. over - into the new TB help?

I was going to backup everything tonight, now I have little to NO hope, without help!

THANKS & remain WELL plus be SAFE!

Just what it says. Using the latest version of Thunderbird on Windows 11 Pro.

I have had my usa.net account use the same IMAP settings forever; I double-checked my settings and they are correct.

Now, I get a LOT of email on that account -- I typically download it when I hit 10K messages. This usually isn't a problem.

I tried moving all of my current Inbox (already in TBird) to my archives. I was then able to download about 1K messages and then it stalled downloading. Said I either didn't have write access to the disk or had a file permission. I'm not seeing anything on the web interface for usa.net on this.

Now, I have 3 other IMAP accounts on T-bird -- 1 is never used (default from my ISP), a 2nd is very light traffic (mostly I stick with that email provider because they are small and still have private shell accounts) and the 3rd is my business vanity domain--high traffic but not the same as usa.net (where I get ALL my receipts for any online purchases, daily newsletters, help forums, etc).

Any idea what may be going on? Please be kind; I am not a programmer, just a more tech-savvy than the average bear (as in if IT is busy at work people ask me for regular stuff).

If any more info/filedump stuff is needed to see what's going on, please do let me know and I will tag it up asap.

Thanks again, community!

OK, so I have 4 different emails on my Thunderbird account. I get the most email from my usa.net (Netaddress.com) account, but that has never been an issue -- as my inbox gets huge I just move the contents into a dated archive.

I have already looped back to the people at usa.net and all of my settings are correct.

Here is the issue: Out of nowhere, a few months ago, when I tried to download my USA.net email, it would stop after 100-200 emails. Also, it would NOT "register back" to USA.net and show the downloaded items as "gone" (I checked my settings; I am NOT leaving email on the USA.net server).

I even tried deleting a ton of emails on the USA.net server side via webmail, and it still just stops after 200 messages max. I then need to dump out what was downloaded to another folder or I get the error below (see upload).

I hadn't changed anything on my settings when this started. USA.net DID start a requirement several months ago RE using SSL, but I didn't have problems when I initially made the switch.

Help, please! When it stops downloading I either get no message, or I sometimes get the message shown.

How to fix please? Again, this is the ONLY email account that I have this problem with; if some kind of "limit" was being hit it wouldn't be letting me download from other accounts, including my "business" email (basically I use USA.net for all of my newsletters, online purchases, etc).

Thanks so much.

11 Nov. I am unable to send or receive e-mail using Thunderbird. I have a gmail e-mail address. When I want to open Thunderbird, I am required to log in using Google. This has just been the case for a few days. Previously, I never had to do this.

It does not work. I cannot log in using Google. I get "Error message 400".

My account settings are: outgoing server smtp.gmail.com incoming server: imap.gmail.com Port: 993 connectivity security: SSL/TLS Authentication: 0Auth. Is there something incorrect in the Account settings?

Sometimes I get a message saying "Authentication failure while connecting to server".

I saw something on line about Troubleshoot Mode for Thunderbird, but I can't get there.

I desperately need to solve this problem. I have used Thunderbird for many years, and have a lot of data in Local folders. I do not want to lose all this data. Thank you.

This is maddening. A couple of days ago TB started to freeze. I have not added any new add-ons. I don't even have any add-ons. I tried one suggestion of repairing and compacting folders and that did not help. I also tried the accessibility.force_disabled change from 0 to 1. It is still happening. I have to use Task Manager to shut it down because if I right-click and close it tells me that TB is already running but not responding when I try to restart it. It takes 4-5 tries to get it to the point where I can have a few minutes to do anything in the program. If I leave and come back, the mail window is frozen. Help, please! I have been using TB for years and never had this problem!

I have successfully added numerous Zoho email addresses for our business into Thunderbird so I can easily toggle back and forth between inboxes, etc., but I have one Zoho email address that I just can't get to add. I created a new App-Specific Password for it in Zoho in case that was the problem, but the new one isn't solving the issue, either. I've attached an image of the screen and the message I'm getting- please let me know where else I can check for whatever might be preventing this add.

I redirect incoming messages into local folders for much of my incoming email. One of my primary sub folders has disappeared. I don't remember doing anything with it – at least not intentionally. It does not show in either the local or primary trash folders. It is not in the archive folder. It is not showing as a sub folder under any other local sub folder. Where did it go and how can I find it?

When I try to download messages from Proton’s inbox, I get this message: “Thunderbird. The current operation on ‘Inbox’ did not succeed. The mail server for account loiscodling@proton.me responded: no such mailbox.. .”

If I access the account directly through Firefox, the inbox is visible with a large number of files in it. Mail in all the other folders on Proton has downloaded correctly to Thunderbird, but not the inbox.

My wife’s Thunderbird has had problems for several weeks. To repair them, I have disconnected from our e-mail provider (Proton.me), & reconnected to it. Everything seems to be fine but her Thunderbird Inbox. There are no emails in it, but it insists there are two (2). I have tried to compact the folder & to repair the folder, but these actions have no effect. How do I get her inbox clear of this problem, so I can focus on her bigger problem?

The New Line (Enter) key always double spaces, which is intended for paragraph text. But for tabular text, this makes unnecessary white space. What key combination generates only a SINGLE new line character rather than TWO of them?

Example: Donor: xxxxx Email: xxxxx Phone: xxxxx Billing Address: xxxxx Bank: xxxxx; Account ending in xxxx

This screen defaults to single spacing; why doesn't Thunderbird allow it?

Incoming mail (txt only; no html) is getting more and more unreadable the last weeks. It looks like in the attached screenshot. I am desperate. What can be the cause of this?

At the same time there are problems with outgoing mail. Characters like 9 or : do not appear on screen although I typed them. When I copy the text to another program, these characters do show. Very annoying. Hope there is a solution to be found somewhere!

Best, Mike

My gmail account in Thunderbird has only two folders, the Inbox and the Drafts folder. so when I delete a message, it lines out the message in the inbox with a single line strikeout and then in order to get it out of the Inbox I have to leave the Inbox and then when I come back to it the message is actually gone from the inbox. When I am using my laptop rather than my desktop computer, all of the folders are there and the messages, when deleted go to the "Trash" folder and are removed from the Inbox. I have been looking for a way to get all of those folders that are normally a part of the other accounts that I have on Thunderbird without success. Is there anyone here that knows how to restore those additional folders to the Gmail account that does not currently display them?

Hello; Windows 10 & current version of Thunderbird. I am trying to add Messages Filters to filter out spam (getting more and more of that!) but the "OK" button on the add message filter is below the bottom of the screen. The window cannot be raised or resized to make the button visible. Photo below. Moving window does not allow me to raise window above top of screen. Keyboard (Alt-Enter) / Move will not work. Changed windows screen size just makes window larger but button still below bottom of screen.

Non-functional work around. Highlight Message name. Press Shift-Tab TWICE. Press ENTER. UGLY!

Tech since DOS 3.0

Thank you for your time and attention.

When I open TB and then open an account, once I click on the inbox nothing happens but if I click on another mailbox like sent or trash, everything works normally so then I can go back and open the inbox. This is random but happens frequently. Mail account doesn't seem to make a difference. Version 144.

I cannot open attachments directly in an email with a double click, Probably since a week or so back. I have to copy the link address and insert it into a web reader. There is no command in the settings as I can see Quite a nuisance, Best regards, Gustaf

Thunderbird just updated to 144.0.1 (64-bit), and now I see a blank area where message list used to be. This true for all accounts and all folders.

I used to see this issue temporarily after compacting folders, but usually (but not always) went away and messages showed up. Sometimes I had to close and restart TB. Now even that wont bring up the lists. I'm dead in the water. And, yes, I did reboot my computer as well. Screenshot of this state attached.

Thanks for any help--it's urgent. Bert

Trying to set up My outlook email account in Thunderbird. Enter the correct info (User and password) and get incorrect password when I am 1000% sure I am entering the correct password but because there is no way to make any manual changes because Mozilla thinks they have everything set correctly, when they don't, I can't add the account. The manual evidently only works if the password is correct?? I can set the account up obviously in Outlook both on PC and both Outlook and Mail app on the IPhone using the same password but not Thunderbird??

I use Thunderbird to access my Hotmail account. I normally work on my Desktop Windows 11 system but have a laptop Windows 11 which I seldom access email with. When I just tried to update the laptop Thunderbird mail I eventually get the Thunderbird message "Unable to write the email to the mailbox. Make sure the file system allows you write privileges, and you have enough disk space to copy the mailbox". There is enough free space on my drive and it succeeded writing 10522 messages before it came to a halt. I notice that the desktop is at 140.4.0 and the laptop is at 144.0.1 and help says they are both up to date.

Since the Desktop mail is up to date it would seem the quick solution is to replace the mail folder on the laptop with a copy of the mail folder from the desktop. Will this be a problem since they seem to be at different versions. Version 140.4.0 on the Desktop and 144.0.1 on the laptop.
