Thunderbird Community Forum

I am installing Thunderbird. I have signed into my email provider using Thunderbird and downloaded my mail. My inbox indicates I have 668 emails. (I accept that as correct because I keep my emails for a long time). Then I went to try to copy my email data by going to ...Thunderbird\Profiles\... I right clicked on my default folder. It indicated only 163 files for the entire folder. It seems to me it does not contain all of my 668 emails. The next step is right click on the default folder, copy then paste in my desired folder on my computer. If I do that, how will I know all of my email files and data will be copied over? Thanks for your help.

I cannot get connected to the ATT.NET server. I have the secure mail key code and have put it in and I still cannot get it to connect.

I thought I had successful auto install W-10 but when I open to send 1st message the"+ new message" button is not active/working. Per article this is how to start. Thanks for help.

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!

Mozilla Thunderbird Email wants to access your Google Account

This will allow Mozilla Thunderbird Email to:

Read, compose, send, and permanently delete all your email from Gmail

See, edit, download, and permanently delete your contacts

See, edit, share, and permanently delete all the calendars you can access using Google Calendar

Mzila Fire Fox that has me perplexed. There is a line that reads, In part….. https://accounts.google.com/signin/oauth/legacy/consent? uthuser=0&part=AJi8hAO27SA1jp0smbnYjSww31z06r6NnelkFAEXAX1pRgQq_2fkoC2lI-Rs0mf3jYCnMSdoG2Gr9V6XDkmWlQydzTYpDy4U-OREnYRGiXK0wIrp32BEL1sC1QyzBm-ZzUFPi6sQw3DCq7hh-HL7ZEAw9QDzw22rmwU7DPjP1nMpdWenxE6fE4LwyjUnAobeE3RPLIWik4O3f5U4lSI1Hwj0AiWBCsLD-

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.

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 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?

Ok I know this has been asked before but I can't find a way to fix this. When I click on ANY link in an email or even the menus, not even the help menu works, I get a "no app associated" error. My file associations for .htm, .html, http, https are all set in the default apps in windows. I can click on an email address and it works just not any other type link. This is in version 144.

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?

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 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.

For the third time now I have found messages I have saved in Local folders in TRASH. I did not put them there, and the original ones in Local Folders are empty. I have had to manually move messages intended to be saved from Trash into my intended folders. I am perplexed why this is happening, as I have not chosen Compact Folders or anything. Very, very annoying. If it continues I will search for another mail tool
