As Outlook online and the mobile app are using a different archive folder than Thunderbird (128.12 on Win 10), I set TB to use the same folder as Outlook (similar problem to here: https://support.mozilla.org/en-US/questions/1168534). But TB is ignoring it and even after unsubsubscribing and deleting the TB archive folder in Outlook, TB is recreating it after archiving the next e-mail. It also ignores the option to put all the mails in one folder and instead creates a one for each year. What can I do?

Hi,

I use Thunderbird as my e-mail client and have been saving e-mails from the inbox into a shared folder on my internal server for many years now. Normally, when I double click to open an e-mail saved into the shared folder, the e-mail will open in Thunderbird and I can click reply, forward, etc. However, since June 17, 2025, whenever I open these e-mails saved in the shared folder, only the subject of the email and two rows of menu bars (i.e., File, Edit, View, Get Messages, Write, Tag, etc.) appear, but the contents of the e-mail do not, including sender information. I've attached a screenshot so you can see what I mean (ignore the black background which I have set). Even though I can click "Messages" --> "Reply" in the menu bar, the composition window that pops up does not show any details of the e-mail I am responding to. However, if I transfer the e-mail file from the shared folder on the internal server to anywhere in my computer, say, the Desktop, the file will open normally in Thunderbird and display all contents normally. Would appreciate it if anyone could help me figure out how to solve this problem. My colleagues and I all need access to these e-mails saved in the shared folder so we can't keep saving them on to our computers. Thanks so much!

Older messages in Thunderbird are listed but their content is not showing. I have been using TB forever and I never had that problem before. It is POP3. When I try Folder Repair, the program simply throws out all messages whose content is not accessible (so if my Sent folder has 40,000 messages it comes back with a Sent folder of 2,000). Clearly something got corrupted but I am not sure what. In the picture below, the header is visible but (a) not clickable (different header showing) (b) no content is displayed. I used to copy the content of the TB folder to my laptop and back (while keeping different profile names assigned during installation. The problem seems to have started when I changed profile names and began using identical profile names on both the desktop and laptop. Also, the total size of the folders is around 65Gb, in case there is a size limit. Any ideas? Thanks

My green "New Message" button has stopped working for some reason. I've tried switching it off then back on but it still won't work. so at the moment I can't create new emails. Regards William

Had a 'Onetel' e-mail address for years and have had the same issues with it a few times where as it just 'drops out.

Have been on here before and received good advice. Last time it dropped out apparently because it didn't know the servers name and that was it it didn't want to play any more. I am determind to get this working again so that I can send from One Tel. It has a Forwarder to another account so I still get the messages. Also have gone in via TalkTalk (who apparently now own Onetel and can receive the messages on my phone (iPhone13) but very hard to reply from it. Any help to get this account up and running from my Desktop gratefully recieved.

Thanks, Dick.

I just updated to version 140.0 and now my subfolders are out of order. Is there a fix for this, short of fixing it manually? I miss how they were automatically alphabetized. That went away when manual reordering was implemented. I can't grab a bunch at the same time and move them, since the order is so messed up.

I exported up my Thunderbird data to an external hard drive from my PC in Croatia which I have been using there for the past year.

I am in South Africa now for a few months and imported the data to my laptop with a new Thunderbird installation.

I have 5 email accounts on one domain, and 1 on another domain.

When I checked for new mail, I was asked for passwords for the 5 accounts on the one domain, and after entering this, the new emails came through fine.

However the one email account on the other domain did not ask for a password, and when I connect I get a message: "Connection to server xxx@xxx.com was reset" I can send emails with this account, but cannot receive any.

Interestingly, I have a previous installation on a desktop PC here in South Africa with the same email accounts. I tried that specific email account and it connects perfectly. The settings are exactly the same.

How do I solve this on my laptop?

There were prob 20 or so, but now just blank tabs. My In Box and incoming email still show OK and I can read those in a new tab. but what about the old ones? And if I cannot recover, how can I remove those blank tabs. Deleting the usual way does not work.

On Windows 10. I wonder if Co Pilot has something to do with it

Thanks Tealeaf

I'm currently on Office Outlook 2021......something happened and the license became invalid....according to Msoft.....I will have to re-purchase.......bought if it at huge discount on ebay so should have expected this... I'm investigating moving to Tbird.....but I have some questions.... 1. The importation of PST file seems rather complicated....is there an easy way to do this...??? 2. In Outlook I use the email....calendar....and notes.....I have a lot of notes as this is how I keep track of what I do for my clients......If somehow I import my PST file into Tbird....does all the email...calendar and notes come with it or just emails...??? 3. I POP Gmail into Outlook....but Gmail requires an App Password......can Tbird handle this..??? 4. My current PST file is about 3gb in size....Can Tbird handle this large amount of data..???

Thanks in advance for any assistance the community can offer... Steve

Hello,

My Thunderbird is on 140.0ESR - just updated yesterday. This morning I am noticing that when I open an email to read, and then close it, my inbox automatically scrolls from the top of the box to the place where that just read email is located. It used to just close and I could open the next one - now it goes through this momentary, fast scroll and then stops at the most recently read. It doesn't seem to matter if there are unread messages in the mailbox - it does the same thing when all messages have been read.

Very strange behavior - and just started with 140.0ESR.

Any ideas appreciated. Thanks!

I have tried searching in my emails in different ways but always get a blank response/screen, which makes no sense - in one inbox or the other, in unified inbox, trying many different words... Using a Nokia Android, if this is relevant .

Thunderbird 140.0 (64-bit)

I cannot reorder some folders within my Local Folders. It only happens with some folders - =not all of them. I can drag and drop the folder to the location I want but for some folders one of the following things happen.

1. The folder immediately return to its original location, that is, I can't move it at all or 2. I cannot drop it where I want but I can drop it in a nearby location and then shuffle the folders around it so it ends up where I want it. For example, if I want to put folder Y between folder X and Z, I can't drop it in that location but I can drop it before folder X (or after folder Z, or in any other nearby location) and then move other folders around so I end up with the correct X,Y,Z order.

In ALL cases, when I exit Thunderbird and then restart it, the folders re-appear in their previous locations - that is, as if I hadn't moved them at all.

This only happens with some folders - and not necessarily the same folders each time - sometimes folders which were in their correct location re-appear somewhere else, but this is a rare event and I've only observed it a couple of times. I have disabled 3rd party backup software in case this was reverse synchronising the files - it was putting the old versions back (a long shot!) but the problem persists.

I have done a clean re-install and are using the default locations provided during the installation.

I could try to create new folders, move the emails to those folders, delete the existing offending folders and then rename the new folders to the desired names and then try move them to the desired locations but this is just a hack and maybe it won't work.

Hi all,

for signing PDFs with my SMIME certificate, another 3rd party software (LibreOffice) uses the Thunderbird profile folder (nssdb stored which is located there). After some investigation by myself, it could be a problem within Thunderbird certificate management itself.

Situation: I've a current and some outdated SMIME certificates for my mail address. But all for one mail address.

Because the current SMIME certificate is not accessible for LibreOffice, I removed temporary all of my outdated SMIME certificates from Thunderbird by the builtin certificate management, i.e. the list of my personal certificates was set to one entry (=the current certificate) in Thunderbird. But even then, LibreOffice lists only an outdated certificate (which is not visible anymore in the Thunderbird builtin certificate management).

Therefore I've checked with certutil the nssdb entries in the Thunderbird profile folder. Surprisingly, there is an outdated SMIME to my mail address contained (no further, even not the current one). Even after removal of those outdated certificates via the builtin certificate management. The current certificate is never listed; always only an outdated one.

This looks like a difference between builtin certificate management and nssdb within the profile folder (or may for another storage location of the certificates)?

certutil -L -d ~/.thunderbird/myprofilefolder --email mymailaddress

Thanks in advance!

Environment OS: Ubuntu 24.04.2 LTS Thunderbird: 128.12.0esr (64-Bit)

How can I stop Thunderbird from displaying its own advertising/donation page on my browser when I open Thunderbird? It opens this page on my default browser, no matter which is chosen: https://www.thunderbird.net/en-US/thunderbird/128.0/whatsnew/?locale=en-US&version=128.6.1&channel=esr&oldversion=102.8.0 If the browser is not open, it will open it.

This is the result of trying to keep Thunderbird from automatically upgrading. In newer versions, the option to choose not to upgrade has digressed from difficult to not available. It did such an upgrade, so I de-installed and reinstalled my original version, only to have this issue.

I was very satisfied with my old version AND see no need for new any of the "features" or look. And, especially, once such a setting is made, don't want Thunderbird, or any other application or app, changing it back. This is a violation of privacy at best.

Worse yet, Thunderbird is attempting to penalize the customer for making a choice on their own computer by infecting the machine with nuisanceware.
