Thunderbird Support Forum

I have created an entry in my Personal Address Book. When I am in that address book I click on the Import tab. I select CSV file. It provides me a File Dialog to select my CSV file. But then it provides me with a File Dialog to select an address book file. The address book I want to use is the one I am currently "in" in the program. But if I for some reason I wanted to import into another existing address book, I should either have to get "in" that one, or it Mozlla Thunderbird would list the address books it knows about as a selection.

It appears I am supposed to select the file that Mozilla Thunderbird created somewhere. From a search it appears (this is on Windows 11) from the App Store that is somewhere in ..\AppData\Local\MozillaThunder.MZL_h<numbers and letters>\LocalCache\<Roaming | Local>.

I don't understand why I am choosing a file that is already open in Mozilla Thunderbird?

The last time I upgraded my long time Thunderbird account, everything crashed and I lost all my contacts and bookmarks! Why should I ever upgrade again? I reported this a year ago or so and never got any response or help.

Hello, I am trying to migrate from my Zoho mail server to Thunderbird, but for the last few days, Thunderbird does complete fetching the remaining emails from the Zoho Server - or so it seems. As you can see in the pictures attached, in the morning I clicked on "Get Messages" and I could confirm that Mozilla connected to the server and started fetching emails (there were more than 3000 emails pending), but after a few hours, I am back to the same amount of emails as when I started in the morning. You can see from the pictures that the inbox has 60,031 or 60,046 (i don´t know which one is correct). However, the most recent email being displayed is dated 03/06/2024 (which is wrong) and then there is a blank between emails from Jauary 11th to May 15th. Could also it be that Thurderbird´s time stamp is wrong? Why can´t I see any of the emails I received today, for example? Any help would be greately appreciated. Thank you. (the attached pictures have the time on the filename.)

Why don’t you guys grow up and just charge money for the application like every other successful app? Stop begging for contributions and just charge a fee for the app. I think you’ll find you’ll do quite well and you’ll stop nagging the rest of us who are paying. You all are stuck in this FOSS ideology. It doesn’t exist, Yes, there have been quite a few “Free“ applications developed, but they were funded by someone donating. Usually some liberal cause. Just charge for the app and move on. You will find that you will have a steady stream of income and you’ll be able to develop it more consistently. You might be able to innovate. Who knows, you might even be able to develop a UI that doesn’t look like it was designed in 1995

Good Morning

Please advise if we can get a solution for this problem.

I have a business email account, its desk space was about to be full

I deleted the account from the c-panel and re construct it again with the same settings.

I discovered that I can`t no longer see the old inbox and sent files, they became empty.

I use Thunderbird to read the email

Is there any way to get the old profile so that i can get the old inbox and sent items

Regards Khaled

TIA , Time to Migrate TB Portable to new computer : I was advised that all need to do is Copy this Folder C:\ThunderbirdPortable to new computer . But that doesn't bring over all my email accounts . Pls , what else do I need to do ? Thanks...

Hi all. I had a hard drive failure and managed to mostly clone the old drive to a shiny new one. There were errors logged during the clone and TB appears to be a victim of those errors.

Win 11 x64.

When I launch TB I get the icon on the taskbar but no main screen. If I hover over the icon I see a small box with the TB logo top left where you’d expect it, and Home next to it. Clicking it has no effect. TB appears to be functioning because new emails are being filtered according to the Rules, as witnessed on my phone.

I tried reinstalling 115.11.1 with no change. So obviously somethings fubar with my profile. What is the best way to proceed? Obviously I’d like to avoid having to set up all my email accounts plus the associated rules etc if it’s possible. I use IMAP if it’s relevant.

Thanks in advance, Tony

My emails do not download into my email "in" box as they used to do. I get the following message when I try to log into my emails.

Warning: Potential Security Risk Ahead

Thunderbird detected a potential security threat and did not continue to live.thunderbird.net. If you visit this site, attackers could try to steal information like your passwords, emails, or credit card details.

Can this be fixed? Can you help me to fix this problem? Thanks, Michael.

Hi, I have been using thunderbird with two accounts. One day one account decided that won't get new messages, so I deleted that account, tried to add it again and it is showing me mistake: Unable to log in at server. Probably wrong configuration, username or password. I am 100% sure, that all the credentials are correct. Could you please try to help me?

i SET UP THUNDERBIRD ON MY NEW COMPUTER, SUCCESSFULLY, BUT THREE DAYS AGO MY WEB HOST/SERVERS UPGRADED THEIR SYSTEM. i SPENT THREE DAYS SORTING OUT NEW SETTINGS. CONFIGURATIONS, PASSWORDS, ETC, TO GET IT ALL WORKING, IT WAS DIFFICUL BUT IT NOW WORKS. HOWEVER, I HAVE MANY FOLDERS OF MAIL ,AND MAIL NOT IN FOLDERS, IN THEUNDERBIRD ON AN OLDER COMPUTER. i WANT TO IMPORT THOSE FOLDERS OF MAIL, AND ADD THEM TO MY NEW COMPUTER THUNDERBIRD INBOX SET UP, BUT I DO NOT WANT TO IMPORT THE OLD SETTINGS AGAIN!" THAT COULD BE A DISASTER. I JUST WANT THE MAIL AND THE FOLDERS. ALL THE VIDEOS i SEE ARE TO IMPORT THE OLD SETTINGS AS WELL. CAN I JUST EXPORT/IMPORT THE ACTUAL MAIL FOLDERS AND MAIL, AND NOT SABOTAGE MY HARD WORK BY CHANGING ALL THE NEW SETTINGS AND PASSWORDS BACK TO WHAT THEY USED TO BE IN THE PROCESS?? IM NOT THAT TECHY; WOULD GREATLY APPRECIATE YOUR ADVICE. THANKS, STEVE

I have added my gmail account to TB and it downloads all the folders and emails correctly, but as soon as I try to move an email with an attachment from a local folder to a folder on the gmail acount I get "Connection to server imap.gmail.com timed out" errors.

I recently setup a new Windows 11 computer and installed the latest version of Thunderbird. I have two email accounts. The gmail account presented no problems. When I tried to setup the AT&T account I first obtained an authentication password and setup the account. While I can send email just fine, the account will not download any email. When I go on the AT&T server directly, there are new, sent and deleted email there. The server settings are set to SSL/TLS and OAuth2. What else do I need to setup before I can mail from the AT&T server?

On Sunday 2nd June I removed and then reloaded Thunderbird, which ceased to function the previous day.. Now I can't send but can receive e mails, and it has lost my entire e mail address list. I need this list to be restored asap, please, so I need advice.

I have used Thunderbird for years. I recently updated to version 115. I prefer the previous version. In 115, I cannot zoom a page simply with ctrl-+ without first going to the view menu. My two Outlook inboxes are sorted at the bottom of my list of favorites and they cannot be moved up with my other inboxes. I had no problems with the previous version. How can I get and reinstall that version?

Hi I did a backup with Zip.file, and then tried to reinstall. Now somme accounts do not have sent/spam/trash Bin folders. When i try to send a mail, i am told that there is not enouch space on the disk to save the message, and that the message will be save in a local folder ? How can I get back to my "old" and working setup Kind regards Michael

Hi, I'm a MTB newbie Version 115.11.1 and am just trying to import my comcast.net address book from CSV. MTB seems to be totally confused about the columns. I'd be happy to adjust the column assignments, as I think I'm supposed to, but it won't let me. The automatically selected column name is the only option allowed in the drop-down. See attached.

Is this by design? Do I need to reorder the columns within the exported file. Seems a bit much really, but ultimately doable, I guess.

Any other options? Or what am I doing wrong

TIA Tim

Tell me how to move, first, andrew@8on8.com, then andrew@luvli-homes.com to you. The latter is with 20i. I do not know where andrew@8on8 is. Please tell me what to do to move these DNs to you.

Hello, Recently I was migrated from Cox email to Yahoo mail and had to change my setting on Thunderbird. The emails work fine, but there seems to a lot of missing folders. I tried to look for the latest backup file, but it does not exist. The latest backup I have is of the year 2022.

Kindly assist me in retrieving my lost folders.

p.s I have searched for the folders under the default profile section but they do not exist.

I installed Thunderbird a few weeks ago and I'm now trying to migrate from Windows Live Mail 2012 (WLM) to Thunderbird (TB). I am connected to a server called Copper..net via IMAP. (I've set up 2 other email accounts under TB, one of which I will almost certainly abandon and the other, I hope, will become my default server. But right now, I'm not really using either).

Most of my emails -- I have over 300,000 -- are stored in local folders. When mail comes into my Inbox, I generally either delete it, mark it as junk, or once read, store it in a local file.

Until yesterday, all of my IMAP folders showed up under the Copper.net account. They also showed up when I went to File subscribe and refreshed the list (other than one episode which I was able to resolve). Now, they don't show up in either place. They still do show up normally in the other accounts.

Since installing Thunderbird, I have managed to transfer most of my local emails from WLM to TB, so I am now down to 3 of my largest folders, containing between 60,000 and 65,000 emails each. Two days ago, I was able to transfer one of them, albeit with considerable difficulties along the way.

My method was to set up a new IMAP folder called Transfers. I COPY emails from the WLM folder to it (in chunks for larger folders). Then MOVE the emails from the TB Transfers folder to the TB local folder.

When everything is working properly, that move eventually results in the TB transfer folder being empty, which then results in the WLM transfer folder being empty. And then I can restart the process.

If for some reason, the move does NOT empty the transfer folder, I do so manually by deleting all the emails and then emptying the trash. I then check properties to make sure that the folder is really empty, and if it isn't, use the tools under properties in WLM to manually delete them

Yesterday, when I tried to do all this again for my 2nd large folder, I found that the transfer box in TB a) often didn't contain all the emails it should have and b) that the ones that showed up as being there wouldn't move at all. I tried compacting, repairing, getting messages, all to force syncing , but nothing worked.

And this morning, things went from bad to worse because now my IMAP folders no longer show up at all (except Inbox and Trash). During this whole time, the inbox has been syncing properly and mostly, promptly.

Finally, I should add that I did download and add the import/export NG tool and while it worked pretty successfully for small folders, if did not work well for larger ones. I'm still in dialogue with the developer.

Any help would be much appreciated; I'm incredibly frustrated.

P.S. I tried this morning to repair TB, just in case, but using Control Panel, the only option was to uninstall it, which I did not want to do. I do wonder whether TB has somehow gotten corrupted.

I also tried opening in safe mode, which didn't help. I shut my computer off at night, so it's restarted at least once a day. Yesterday and today, I also restarted during the day in hopes that it might help. No dice.
