Forum Thunderbird zajednice

I'm using TB 150.0.2 on a Mac with the latest update of MacOS.

I just deleted all of my archived emails, thinking it was stuff that I had sent to trash. I.e. I deleted all archives, then emptied trash. Only after I did that did I realize that I had deleted things I want to save.

I'm pretty sure there's no way to undo emptying the trash, but I use Time Machine to back up. If I open time machine and go to the most recent back-up, I should be able to get everything back, right?

What folder (or folders) should I restore from a Time Machine back-up?

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?

I use Thunderbird and received a message about an update which I allowed. I went to another app and when I checked Thunderbird all of my data is gone. The only folder Mozilla Thunderbird folder reads: tobedeleted. It is empty. All of the data is gone. Is there a way to retrieve it? PD - [edited from public] @gmail.com. My desktop runs Windows 10 only.

Mail filters for custom headers like List-Unsubscribe, Authentication-Results or Received-SPF copying messages from IMAP accounts to Local Folders do not work on the Yahoo! IMAP account. For example:

filter1.jpg: name="_Inbox2: List-Unsubscribe <https" enabled="yes" type="17" action="Copy to folder" actionValue="mailbox://nobody@Local%20Folders/Inbox/_Inbox2" action="Stop execution" condition="OR (\"list-unsubscribe\",contains,<https)" (should copy messages from IMAP folders to _Inbox 2 on Local Folders)

filter2.jpg: name="Spam: Authentication-Results dkim=unknown | Received-SPF fail | X-Antivirus-Status Infected" enabled="yes" type="17" action="Copy to folder" actionValue="mailbox://nobody@Local%20Folders/Junk" action="Stop execution" condition="OR (\"authentication-results\",contains,dkim=unknown) OR (\"authentication-results\",contains,dkim=perm_fail) OR (\"authentication-results\",contains,dkim=none) OR (\"received-spf\",begins with,fail) OR (\"received-spf\",begins with,softfail) OR (\"received-spf\",begins with,none) OR (\"x-antivirus-status\",is,Infected)" (should copy messages from IMAP folders to _Inbox 2 on Local Folders)

But filter3.jpg works well: name="Inbox" enabled="yes" type="17" action="Copy to folder" actionValue="mailbox://nobody@Local%20Folders/Inbox" condition="OR (subject,doesn't contain,t[k\6iq69pd+}'cr)" (copies all remaining messages from IMAP folders to Inbox on Local Folders)

(the snippets above are fragments of the msgFilterRules.dat file)

Filters1 and 2 work well on other IMAP accouns, like for example wp.pl. So this is about Yahoo or something is corrupted. My question is, what wrong is here ? And by the way - how to create filter copying all messages from IMAP to Local Folders ? Is better way then filter3 looking for random string in the subject or somewhere else ? Thank you.

How do I import *.ICS file in a reasonable amount of time. I have appointments in an ics file of less than 1 K in size, typically 700 - 800 bytes in size and they take HOURS to import and do not connect properly then to allow editing the appointment. This is from Baylor Scott and White, a major hospital system in Texas. If there is a problem with the imported file structure, please point me to the correct file structure. I like Thunderbird, but this part of the calendar is very frustrating. Clarence

Hi,

I have been using Thunderbird as my preferred email client since around 2004 on Linux, macOS and Windows.

I am current running Thunderbird 150.0.2 64-bit on macOS Tahoe 26.5 ( Intel ).

When I attempt to create a new 'Folder' or 'Sub Folder' on either an iMAP account or, more importantly, my 'Local Folder' the displayed dialogue box is sized incorrectly and I am unable to complete the action.

Specifically I can type into the 'Name' text box and see the 'Create as a subfolder of" drop down dialogue but the two buttons below are barely visible and I cannot select either with my mouse. Nor can I resize the dialogue box itself [ make larger ] to enable to be select either button.

I can use the <TAB> key to cycle thorough the various items and the <RETURN> key to select an option.

I have attached a sample image of the issue.

Thanks.

I have everything I need from my old machine except my e-mail filters. If I copy the whole profile I will lose all of the sent messages and saved messages I have generated since I got Thunderbird up and running on my new machine.

I have tried multiple times to setup a new Outlook email to Thunderbird. I already have one setup and that's fine, but when trying to connect my new email account I keep getting the error

exchange auth error

I've tried everything to fix it.

The setup configuration all goes well, but then connection just won't happen. I've checked in Outlook and I have given Thunderbird permission but still it won't work.

I have the latest Thunderbird on my laptop. I have turned off the hub, but it still appears when I add an account. Sigh!

Please help!

Ever since one of the recent updates, my new email notification box is showing up on wrong monitor. I have a 2 monitor setup, the notification box is now showing up on the second monitor. I have tried turning the option off and back on but makes no difference.

I'm on a new Windows 11 desktop with two monitors. Everything's been working just fine up until around 26th April (two weeks ago) when the native Thunderbird new mail notifications started appearing in my second monitor, rather than my main display. I had made no changes at all myself.

I've been through all the fixes suggested via Google (toggling the displays; checking Windows notification settings), but none of those fixes have made any difference. I switched to using Windows system notifications for a while, but I really don't like them.

Might this be something in a Thunderbird update itself? It just doesn't seem to be detecting the primary monitor at all. All my other app notifications continue to show on the primary display.

Has anyone else encountered this or have any other solutions I could try?

Thanks, Averill

I am unhappy with version 150 of Thunderbird. In earlier versions, I was able to access the full range of emojis when writing an email. That is no longer possible; I can now only access a few. The integration of add-ons with Thunderbird isn’t working properly. After adding the German dictionary, Thunderbird froze; after adding ImportExport Tools, Thunderbird not only crashed but also wouldn’t start up again.

I start to make a new email message. I start typing in the recipient's email. Auto-complete finishes the address but misspells it. The recipient's email in all the address lists have it correctly. I recently saw the light and came over from Outlook. I imported my Outlook address list. It was correct in Outlook. Newest version of Thunderbird. thunderbird-MSIX - 1.0

Tags summary display has disappeared.

I can search for tags, but the convenient "tags folder" is gone. Please help.

Tried in safe mode with add-ons and toolbars/controls disabled. Error console is empty when assigning or removing tags.

I use the filters in Thunderbird a lot, so I am familiar with the setup. I need to automatically forward a message to my wife if it comes in from a specific email address. I cannot see a way to do this. Is it possible?

Version 140.10.2esr | Released May 8, 2026 I get this message every time: Sending of the message failed. The message could not be sent because connecting to Outgoing server (SMTP) mail.twc.com failed. The server may be unavailable or is refusing SMTP connections. Please verify that your Outgoing server (SMTP) settings are correct and try again.

Thank you, George Correia
