I use Thunderbird 128.2.0esr (64-bit) to read mail from the Outlook server; these are the folder mappings:

imap://<email>@outlook.office365.com/INBOX imap://<email>@outlook.office365.com/Sent imap://<email>@outlook.office365.com/Drafts imap://<email>@outlook.office365.com/Trash

I used to also be able to read the Junk Email folder from the Ourlook server the same way, but the folder disappeared from my Thunderbird a couple of months ago. I tried re-adding it as a sub-folder, which is how I created it in the first place, but it won't appear on the list.

I'm not sure what else to do here. I don't know where the Thunderbird directories are stored locally any more, I'm using Ubintu 24.04.

I have 21 filters set up in Thunderbird (originally on the Mac, now on Windows). This is for an IMAP account.

Most of the filters are simple, one match, mark message as read, move to a folder. A few have multiple matches, but the same mark read and move to folder steps.

Some filters work fine, some do not work at all. The ones that are not working are the simple single match ones. There's nothing in the filter log showing what the issue might be. The filter in question doesn't show up.

What can I do to track down what the issue might be?

Thanks.

I’m on Thunderbird 148.0.1 (aarch64), and having an issue each time I go to my Sent folder. What happens is this. I try to select an email I just sent minutes ago, and Thunderbird scrolls down to almost the last sent email (in my case, as I keep everything, that email could be years old).

This is only on my M1 MacBook Pro, as on my 2018 Intel Mac Mini (both systems are running Sonoma 14.8.4 I can select any recent email in my Sent folder and the selection stays.

I use Thunderbird on Windows 10; I have a verizon.net email account which I access through Thunderbird. Verizon.net email is transferred to the server from AOL Mail, and I have been able to get and send my emails on Thunderbird at verizon.net for years. This week, after Thunderbird's latest update, I have not received any incoming mail on Thunderbird, but I can see my emails on AOL Mail. The technical expert I consulted deduced that the problem is with Thunderbird such that AOL is not connecting to the incoming mail server, even after the password was changed. I can send messages successfully from Thunderbird; the outgoing mail works.

Oh, woe is me. I had both Thunderbird and Firefox open on my desktop, and thought I was typing into Firefox's address bar. But Thunderbird was actually 'live' (selected?) on the desktop, so that's where my keystrokes went. Not sure what I typed or where the cursor was, but suddenly I have two folders in the left Thunderbird pane that I can't figure out how to get rid of. They are both just above my Local Folders: Templates and Archives folders for one email account, and an Archives for another. All three folders are empty (Archives had "2025" subfolders, but I was able to delete those). Keyboard strokes generated these, but they don't delete. What can I do? Can I navigate with Windows Explorer to where these folders actually reside and delete them there? I sure don't want to mess anything up. Many thanks in advance!

Bonjour, récemment j'ai dû reinitialiser windows 11, j'avais fait un backup avec ashampoo backup. Après reinstallation de thunderbird, je voudrais restaurer le donnés et surtout les archives. J'ai restauré les données dans de profile, mais je ne vois pas les anciens messages ,calenders et contacts. J'ai lus dans les forums , de recharger la version 141, pas de succès. J'ai lu aussi d'effacer global-message-db.sqlite , pas de succés. Que doit je restaurer, et dans quel version ? Merci pour votre aide. André

Dell tech reinstalled Windows 11, but missing info on my local folders now on 2nd drive. I have iDrive backup of both the drives, need help to find what I need. I'm Tbird supporter monthly and at other times. Sure can use some help as need some financial records that were in local folder files.

Appreciate help to find and restore my Local Folders which held the needed data.

Thanks in advance, Kelly

On 29 Nov 2024, TBird stopped downloading all emails from all my accounts. I have not changed anything on the computer and have run all the troubleshooting routines I can find for TBird. Still not working. Interestingly, when Better Bird import the settings from TBird, it exhibited the same issues. Any suggestions?

TIA

I was cleaning up my Inbox when I looked at the "Important" folder. I read in a number of places that this is a "Gmail" thing, and messages get in this folder apart from any action etc on my part.

I have a couple questions.

FIRST, are the emails in the "Important" folder only in that folder or are copies in there? I deleted a number of 2 to 3 year old emails that I do not consider important today. The closer I get to this year [2025], the more careful I get.

SECOND, how can the auto-population of that folder be stopped and the folder be deleted? I keep my important emails in designated folders so I can find them.

Thanks in advance

I have the same issue and behavior reported in question 1468895 following update 128.3.1esr.

When I "get new mail," another account processes and my main one does nothing with no status message display. It used to be that when "nothing" happened, I would try again and be asked to confirm a security exception and then it worked again.

A tablet pc I use for travel with the same update continues to download mail for this account, though more hesitatingly than it did.

The error console shows: NotFoundError: No such JSProcessActor 'BrowserToolboxDevToolsProcess' pop3.server1.4: SecurityError: a SecurityCertificate error occurred Pop3Client.sys.mjs:380:18 pop3.server1.4: SecurityError info: SSL_ERROR_BAD_CERT_DOMAIN Pop3Client.sys.mjs:422:20 pop3.server1.4: SecurityError cert chain: securepop.siteprotect.com; serial# 20:C8:AF:E0:B1:95:42:48:9C:C8:21:21:4A:87:89:B8 <- Avast Web/Mail Shield Root; serial# 4D:D7:A4:81:AF:9D:DF:4D:8F:45:D8:21:07:23:2D:0A Pop3Client.sys.mjs:427:22 tb.account.size_on_disk - Truncating float/double number. 2

I turned off the antivirus email feature and then it read: NotFoundError: No such JSProcessActor 'BrowserToolboxDevToolsProcess' pop3.server1.4: SecurityError: a SecurityCertificate error occurred Pop3Client.sys.mjs:380:18 pop3.server1.4: SecurityError info: SSL_ERROR_BAD_CERT_DOMAIN Pop3Client.sys.mjs:422:20 pop3.server1.4: SecurityError cert chain: securepop.siteprotect.com; serial# 0F:F0:5D:99:50:38:74:73:10:57:9F:F7:75:85:06:4A <- GeoTrust TLS RSA CA G1; serial# 0D:07:78:2A:13:3F:C6:F9:A5:72:96:E1:31:FF:D1:79 Pop3Client.sys.mjs:427:22

Dear Sir or Madam,

I have lost all stored folders with my email correspondence from the Local Folders for an unknown reason (I restarted my computer, and they disappeared). I can find some of these emails using the search option, but I cannot see the path of their storage location. I have checked my Profile/Mail/Local Folders, but they are not there. Are they stored on the server? How can I recover these folders?

Thank you very much in advance,

Jasmina

I have a local folder which has 90 folders within it. These are folders brought over from Eudora (the mail system I used before Thunderbird). It would help me if I could easily move all 90 from their current "Eudora" folder to the big "main" folder that Thunderbird has. To make it clear what I'm asking, here's an example, using two folders, Danbury and Fritz.

D (folders whose names begin with D) Eudora folder, which has two folders - Danbury and Fritz F (folders whose names begin with F)

Is there any way to move the 2 folders that are currently within the "Eudora" folder so that they're "first level" folders. In other words, Danbury would be among the "D" folders and Fritz would be among the "F" folders.

The only way I know to achieve this is by manually creating the new folders, moving the items from the old folder to the new folder, and then deleting the old folder. This is cumbersome.

Hi. I have created 2 subfolders in "Drafts", which ALSO turned into draft folders:

• The folder icons switched from the standard folder icon to the "Drafts" icon.
• The right-click context menu is reduced (just like for other special folders), e.g. the "delete" command is missing.

So how can I delete this misbehaving folder now ?

I doublechecked in my account manager and via config editor that the subfolder are NOT used as DRAFTS folder for any of my (POP3/maildir) accounts.

Thank you so much.

I keep my mail (both sent and received) in local mail folders. My server is gmail, and sent mail is put in gmail's sent folder by default. Every few months, I copy those messages to a local folder, and after I back them up, I delete the server copy.

What to my dismay, I discovered today that only the message headers, and not the messages were present in the local folder, though they had been when downloaded. Looking at the file sizes, I found the sent file to be 0 Kb, and sent.msf 255 Kb, when sent should have been around 60 Kb long.

I have been able to restore the messages from backup (whew!), but I have no idea how then sent file was wiped out. I know I did not do it.

Has anyone else had this happen? Is there a preventive measure I should take?

After Thunderbird just updated to Version 128.5.0esr today, now all my accounts are saying that the connection is refused. This is coming from three different email services that I have accounts on. I'm assuming it's not an issue with those servers as I can access them just fine with a different email client, and I didn't change any settings. Yesterday it worked, today it doesn't. Only thing that seems to have changed is Thunderbird got updated.

Dear community,

I'm planning to change my email provider and during the transition period I need to have the old and new accounts running concurrently. The help article states:

".....you can create additional profiles, each with their own set of account configurations, messages, etc. (Note, each profile can access multiple email accounts''.) .

but I can't see how this would work. If anyone can explain in simple terms how to achieve this, or point me to the relevant information I should be most grateful.

A while back I managed to both widen my sliders and change the color to improve visibility from the grey that is barely different from the background color. It work most of the time, I made the change tinkering with GTK. Here's my gtk.css file:

scrollbar { background-color: #cccccc; } scrollbar slider { min-width: 20px; }

/* dark green: pointer is not in the active window */ scrollbar slider:backdrop { background-color: #00aa00; }

/* green: pointer is in the active window but not on a slider */ scrollbar slider { background-color: #00ff00; }

/* dark red: pointer is hovering over slider but mouse button not pressed */ scrollbar slider:hover { background-color: #aa0000; }

/* red: slider is active */ scrollbar slider:hover:active { background-color: #ff0000; }

... it always works in the 'inbox' window and usually works for message content, but some messages insist on continuing to show the tiny grey slider that's almost invisible. Is there some way I can fix that? If anyone's interested I can forward examples of both situations. Image on the left is what I want. Image on the right is the tiny grey slider that I can't see.

Recently, I have experienced an erroneous browser launch, simply by clicking on the title of the message in the list pane. This problem seems to occur when clicking on emails from a particular UK supermarket (tesco.com) and the web page opened has a long and complicated URL, but the page contains only a single pixel which shows up as a white dot on a black background.

Obviously, it is likely that there is something strange about that source, but the problem doesn't occur if I click on the same email in a different email client (in this case Evolution).

I have tried various Settings as advised by web searches and also the solutions suggested in Thunderbird Help (Troubleshooting Mode and Troubleshooting Information).

I am running Thunderbird 140.5.0esr (64-bit) on Kubuntu Linux 24.04.
